Estimating shear strength of high-level pillars supported with cemented backfilling using the HoekeBrown strength criterion

Deep metal mines are often mined using the high-level pillars with subsequent cementation backfilling(HLSCB)mining method.At the design stage,it is therefore important to have a reasonable method for determining the shear strength of the high-level pillars(i.e.cohesion and internal friction angle)when they are supported by cemented backfilling.In this study,a formula was derived for the upper limit of the confining pressure σ3max on a high-level pillar supported by cemented backfilling in a deep metal mine.A new method of estimating the shear strength of such pillars was then proposed based on the Hoek eBrown failure criterion.Our analysis indicates that the horizontal stress σhh acting on the cemented backfill pillar can be simplified by expressing it as a constant value.A reasonable and effective value for σ3max can then be determined.The value of s3max predicted using the proposed method is generally less than 3 MPa.Within this range,the shear strength of the high-level pillar is accurately calculated using the equivalent MohreCoulomb theory.The proposed method can effectively avoid the calculation of inaccurate shear strength values for the high-level pillars when the original HoekeBrown criterion is used in the presence of large confining pressures,i.e.the situation in which the cohesion value is too large and the friction angle is too small can effectively be avoided.The proposed method is applied to a deep metal mine in China that is being excavated using the HLSCB method.The shear strength parameters of the high-level pillars obtained using the proposed method were input in the numerical simulations.The numerical results show that the recommended level heights and sizes of the high-level pillars and rooms in the mine are rational.

Leave or Stay?Antecedents of High-level Talent Migration in the Pearl River Delta Megalopolis of China:from a Perspective of Regional Differentials in Housing Prices

Rapid urbanization and population growth have triggered an increase in urban housing demand and rising housing prices,which can influence the migration intention of high-level talents.Much work within the literature has focused more on the migration of the general public.However,antecedents of migration intention and the impact of housing prices on the migration of high-level talents remain unclear.Therefore,based on the push-pull theory,this study investigates the influencing factors of talent migration intention and explores the role of housing prices.This study reveals a complex mechanism underlying migration decisions by using logistic regression models and survey data of high-level talents in the Pearl River Delta(PRD)megalopolis of China.The results indicate that:1)in high house-price regions,social integration is the primary push factor,and the main factors for retaining talents are the expectation of future work and intimate family relationships;2)in medium house-price regions,the main factors that attract talents are the current salary level and close family ties;3)in low house-price regions,living convenience is a determining factor in retaining talents.This study provides a new perspective for talent mobility research and offers valuable inputs for retaining and attracting talents in different economic development regions.Findings are of great significance for formulating talent introduction policies and forming a new pattern of rational spatial docking and effective allocation of human resources.

认知术语学视角下中药材命名研究——以《海药本草》为例

为揭示中药材命名背后的认知机制,促进其翻译的规范化,通过对《海药本草》收录的131种药材命名方式进行分类和量化统计,发现其中86种药材主要基于入药部位、形状、音译、传说、功效、生长环境、生长特性、颜色、产地等单一特征命名,另45种药材则整合“音译+气味”“产地+气味”“形状+气味”等两个或多个特征命名。文章认为药材无论是基于单一特征命名还是整合多个特征命名,都是用突显、易辨认、易感知的部分特征来代替整体,反映了概念转喻在药材命名中的重要作用。当单个特征不足以界定药材时,人们会无意识地整合多个特征来命名,体现出概念整合在中药材命名中的普遍性。此外,人们往往借助所熟知的事物与药材在形状或功效上的相似性来命名,体现了概念隐喻在中草药命名中的作用。入药部位、形状、药效、气味、产地等与药材的功效和辨认密不可分,因此会被突显出来用以命名。《海药本草》以收录海外药为主,在命名中直接音译最为省力,这使得音译命名方式占据比例也较高。

国内外转喻研究现状与趋势--基于CiteSpace的知识图谱分析

利用CiteSpace对2000—2020年间WOS和CNKI数据库中的转喻研究文献进行可视化分析,梳理国内外转喻研究的现状与发展趋势。国内外转喻研究深入发展,但国内转喻研究成果的国际发文影响力还有待提高;多数学者更倾向于独立研究,学术交流与合作较少;国内外的研究热点均涉及转喻的本体研究、转喻与隐喻的关系及转喻在不同语言层面的应用。国外学者的研究热点更广泛,且采用多样的实证研究方法;国内外研究热点的演进趋势不完全同步。另外,国外前沿研究话题较为多元,而国内前沿话题相对单一。总之,转喻研究虽已取得巨大成就,但仍存在诸多研究空间,需要国内外学者继续深入探讨、挖掘。

英语修辞手法metonymy与synecdoche用法辨析

metonymy与synecdoche是两种常用也难以区分的修辞手法。两者既有联系,也有区别。在英语专业高年级阶段,特别是在高级英语学习过程中,学生很容易将它们搞混淆。笔者查阅了大量英语修辞资料发现,很多学者也未能就二者的具体差异达成一致。

Metonymy:借代与转喻

Metonymy在汉语中有两种译法:一是"借代",二是"转喻、换喻"。本文用认知语言学的观点探讨metonymy的译法问题,认为metonymy有的有"喻",有的无"喻;"有的有指代性,有的无指代性。因此,metonymy有的可译为"借代",有的则可译为"转喻、换喻"。我们试图得出这样的结论:无"喻"有"代"的metonymy(如"The pot is boiling)"是"借代",有"喻"无"代"的metonymy(如"Mary is just a pretty face)"是"转喻",有"喻"又有"代"的metonymy(如"The crown has notwithheld its assent to a Bill since 1707.)"则译为"借代"或"转喻"皆可。此外,从原意、非原意无喻借代、非原意有喻转喻到隐喻,实际上是一个连续体,它们定义清楚,但边界模糊,有许多问题还值得进一步深入探讨。

汉语借代和英语Metonymy的对比与翻译

汉语修辞格借代不仅与英语Metonymy相似,而且还包含英语修辞格Synecdoche和Antonomasia。它们在结构上和修辞作用上都彼此十分相似,而在相似之中又存在一些差异,因此,把它们加以对比,进行分析,有利于我们的英汉翻译工作。

Metonymy和Metaphor的英汉修辞比较

借代和借喻是英汉语中两种重要的修辞格,由于二者均涉及词义的转化,因此两种辞格容易混淆。本文指出了借代和借喻是两个不同的概念,阐述了借代和借喻的不同类型,在此基础上,本文从两者所构成的客观基础,两者中本体和借体喻体的关系,两者的转换方法和表达效果四个方面分析了两者的不同之处。

Effect of drying cracks on swelling and self-healing of bentonite-sand blocks used as engineered barriers for radioactive waste disposal

Experiments were conducted to evaluate the healing of drying cracks in air-dried bentonite-sand blocks after hydration and swelling in groundwater,providing justifications to simplify the protection of blocks prior to installation in a high-level radioactive waste repository.Synthetic groundwater was prepared to represent the geochemistry of Beishan groundwater,and was used to hydrate the blocks during the swelling pressure and swelling strain measurements,as Beishan is the most promising site for China's repository.Healing of the surface cracks was recorded by photography,and healing of the internal cracks was visualized by CT images and hydraulic conductivity of air-dried blocks.The results indicate that the maximum swelling pressure and swelling strain are primarily affected by the geochemistry of Beishan groundwater,but not affected by the drying cracks.The maximum swelling pressure and swelling strain of air-dried blocks are comparable to or even higher than the pressure and strain of fresh blocks.The maximum swelling pressure measured in strong(i.e.high ion strength)Beishan groundwater was 44%of the pressure measured in deionized(DI)water,and the maximum swelling strain was reduced to 23%of the strain measured in DI water.Nevertheless,the remained swelling of the blocks hydrated in strong Beishan groundwater was sufficient to heal the surface and internal drying cracks,as demonstrated by the pictures of surface cracks and CT images.The hydraulic conductivity of the air-dried block permeated with strong groundwater was comparable(3.7×higher)to the hydraulic conductivity of the fresh block,indicating the self-healing of drying cracks after hydration and swelling in groundwater.A simplified method of protecting the block with plastic wraps before installation is recommended,since the remained swelling of the block hydrated in Beishan groundwater is sufficient to heal the drying cracks.

区别Metaphor和Metonymy的一种方法

由于隐喻和借代均涉及词义的物化，因此这两种辞格容易混淆，修辞学界对这两种辞格的区刑亦尚无定论。笔者依据人类心理相似联想和相邻联想的思维模式，提出一种区别隐喻和借代的方法，即看ＸｉｓＹ是否成立（其中Ｘ是被代物，Ｙ是用来替代的物体）。成立就是隐喻，否则就是借代。

英语Metonymy和汉语“借代”之比较

英语Metonymy和汉语的"借代"都是在这两种语言中使用非常普遍的修辞格之一。本文通过对英语Metonymy和汉语"借代"这两种修辞格在定义、表现形式及修辞功能上所进行的比较研究,旨在表现二者之间存在许多的相似的特点,以及其不同之处。同时也希望通过对二者之间的比较,以便更好地区别二者异同,正确地判断和应用这种修辞格。

汉语修辞的借代与英语的Metonymy & Synecdoche

大学的英语教学如果徘徊在扩大词汇量和加强语法概念的巩固和进一步深入上 ,学生无疑会走入歧途。学习英语的学生 ,不论是专业的或非专业的 ,高分低能现象的出现就是一个很好的例子。在与外国人的交流中 ,学生们往往会感到自己所要表达的思想和感情常常是不到“火候”,说不到或写不到“点子”上。这并非是因为学生的词汇量小 ,抑或是因为学生的语法知识欠缺 ,而是因为我们忽视了语言中更深一层的内容——即语言中的修辞。我们不是常说“话有三说 ,巧说为妙”吗 ?要想巧说 ,学习一点修辞知识则是必不可少的。

传播修辞学视角下《宠物医院》中的概念转喻与共情效应研究

《宠物医院》是国内首档宠物医疗观察类真人秀节目,以纪实性的拍摄手法形塑了潜含转喻意蕴和情感共鸣的视觉传播符号。本文以传播修辞学为理论来源,移植伯克的戏剧“五位一体”理论及其后来所补充完善的“态度(attitude)”要素对节目文本符号进行分类。同时,用质性研究视角中的文本分析作为研究方法,以学者刘涛的“视觉转喻理论框架”作为分析基础,将共情效应作为研究旨归,从像似指代和规约指代两种转喻关系出发,研辨节目中概念转喻的本体特征和喻体意涵,以及由概念转喻所产生的共情效应。此外,在共情效应的研究中,引入学者胡范铸等所建立的“共情修辞”研究方法,实现与概念转喻研究在修辞学意义上的顺连,以及共情效应研究本身的内容构建。

关于日语“青”的比喻义的研究

色彩词是日常生活中最常用的语言,随着社会文化的发展,色彩词的词义逐渐扩大,发展出了很多本义以外的引申义。而作为色彩范围最广的“青”,其演变出的引申义更是丰富多彩。本文以日本字典中收集的青词汇为中心,从认知语言学角度分析并探明“青”的比喻意义。得出结论:1.青的比喻意义:不成熟、青色衣服、地位低、春天、新鲜、绿叶、青眼、绿色的作物、喜欢、墨、蓝天、安全、蓝纹陶瓷、蓝色染业、青草、年轻等;2.青的比喻意义的产出和青色的特征及日本文化和外来文化影响有关。

汉语修辞格中的“借喻”和“借代”与英语中的Metonymy, Antonomasia and Synecdoche

通过对汉语修辞格中的借喻和借代与英语语言学中的Metonymy,Antonomasia和Synecdoche的比较和对比,阐明几者之间的关系,即:英语中的Metonymy并不等同于汉语的"借喻",而是在修辞层面上与汉语的"借代"相对应;英语中的Antonomasia只是Metonymy的一种,即以专名代泛称,英语中的Synecdoche同样也只是Metonymy的一种类型,即以部分代整体或整体代部分。

语法转喻框架下“N的V”结构的形成机制研究

汉语“N的V”结构一直是学界探讨的热点问题之一。从语法转喻视角,架构“N的V”结构的理论分析框架,并基于CCL中的真实语料,可探讨其形成机制。研究表明,动词V进入“N的N′”构式的中心语N′位置,受到该构式的压制,从表动作的源概念转喻为表事件的目标概念;“N的V”的概念转喻触发其语法结构变化,体现在对动词V属性的重新范畴化和该结构作主、宾时对句子谓词的选择上;“N的V”的语法结构对其概念转喻有制约作用,体现在该结构的语义指称性和N与V的语义关联度上;语境对“N的V”结构的概念转喻和语法结构之间的双向互动具有调控作用,体现在单音节动词进入该结构的允准条件和“N的V”结构歧义的消解上。
