Construction and Practice of First-Class Courses on Virtual Simulation Experimental Teaching of Urban Overpasses

Virtual simulation experiment,as a new way to promote the digital transformation of education,has a broad development prospect and application value.The civil engineering experimental volume and space are huge,it has a long construction period,is highly dangerous,and is difficult to experiment with.In order to solve the contradiction between the traditional theory teaching of civil engineering and the engineering training of students,the construction of virtual simulation experimental teaching courses with a high degree of realism,intuition,and accuracy can be used as a useful supplement and innovation of experimental and practical teaching.This paper takes the virtual simulation experimental teaching course of urban overpasses as an example,introduces the necessity and practicability of the course construction,and describes the experimental principle structure of the course,the simulation scene design,the experimental teaching process,the experimental method,etc.The course has achieved good application results,and it has been recognized as the first-class virtual simulation teaching course of the Chongqing Municipal Government,which provides certain references to the construction of the same type of courses in the civil engineering profession.

Construction of University Librarian Team in the Context of Double First-Class Initiative

Data services,knowledge services,and information services are the core service elements of university libraries in the context of the Double First-Class Initiative.Combined with the current situation of insufficient overall service capacity of libraries,this paper proposed strategies and implementation paths for optimizing the service system from three aspects:the construction of the professional qualification system for librarians,the establishment of post institutions,and the construction of library culture.Long-term path:putting library human resource management into the legal track,taking the lead in local legislation,and promoting the construction of library legislation and professional qualification certification system;optimizing the personnel system,implementing hierarchical management and classified assessment for professional librarians and auxiliary librarians.Short-term path:intensive post allocation,namely,assigning the core strength in the core post,and tackling the temporary major work combining multiple forces in the form of a"working group";building an open knowledge service ecosystem,accelerate the cross-border integration of libraries and other organizations,and striving to build the core competitiveness of libraries.

Penalty model for delay of bidding section construction period in South-to-North Water Diversion Eastern Route Project from perspective of programs

According to the multi-project and program management theory, this paper analyzes the program generation principle and establishes a program based on progress goals. On the basis of the present situation of calculation of penalty for delay of the bidding section construction period with the critical path method, we studied the effects of contractor-induced delay of the bidding section construction period in detail, including the effects on the construction period of the bidding section itself, the earliest start times of the next bidding section and other subsequent bidding sections, and the construction period of the program, and then constructed a penalty model for delay of the bidding section construction period from the perspective of programs. Using the penalty model, we conducted a practical analysis of penalty for delay of the construction period of the Baoying station program in the South-to-North Water Diversion Project. The model can help determine the amount of penalty for delay of the construction period in bidding sections scientifically and reasonably,

Small Town Construction in the 13th Five-Year Plan Period: A Case Study of Shangrao City

The 12 th Five-Year Plan period was unusual five years in the development of China. Under the dual pressure of complex international environment and arduous domestic reform task,China made outstanding achievements in economic development,which lays a solid foundation for building a moderately prosperous society in all respects in the 13 th Five-Year Plan period. The key and difficult points of building a moderately prosperous society in all respects lie in solving issues concerning agriculture,farmers,and rural areas. The 18 th National Congress of the CPC stated that integrated urban and rural development is the fundamental approach for solving issues concerning agriculture,farmers,and rural areas. As a transitional form from rural areas to urban areas,small town play an important role in integrated urban and rural development. In the 13 th Five-Year Plan period,China should take a new road of characteristic urbanization,energetically develop key towns,central towns,and characteristic towns,use points to drive areas,and promote coordinated progress of urbanization construction and new countryside construction. Focusing on the objective of building a moderately prosperous society in all respects and taking Shangrao City as an example,we analyzed construction of small town,in order to provide scientific theoretical reference for urbanization development,plan preparation,and policy formulation of Shangrao City.

Risk Assessment and Prediction of Construction Project Based on 1D-CNN-Attention-BP

In order to solve the problem of low accuracy of construction project duration prediction, this paper proposes a CNN attention BP combination model project risk prediction model based on attention mechanism, one-dimensional convolutional neural network (1d-cnn) and BP neural network. Firstly, the literature analysis method is used to select the risk evaluation index value of construction project, and the attention mechanism is used to determine the weight of risk factors on construction period prediction;then, BP neural network is used to predict the project duration, and accuracy, cross entropy loss function and F1 score are selected to comprehensively evaluate the performance of 1d-cnn-attention-bp combined model. The experimental results show that the duration risk prediction accuracy of the risk prediction model proposed in this paper is more than 90%, which can meet the risk prediction of construction projects with high accuracy.

五四时期《资本论》传播力建构的翻译赞助之道

五四时期,《资本论》在中国的传播实现了前所未有的成功,从而进入了中国政治思想文化的中心,有力助推了中国革命的新民主主义转向。五四时期《资本论》传播力建构的成功,得益于五四精英多元互补的翻译赞助策略。通过赞助推出简明的阐释性文本强化《资本论》学理的易解性,在《新青年》等报刊刊文介绍、评论与节译强化传播广度,筹划马克思主义研究会等社团的译介与研究活动、演讲、授课及与进步力量积极互动强化传播深度和力度,五四精英有力赞助了《资本论》的中国传播。五四时期《资本论》传播力建构的翻译赞助之道对当前中国化马克思主义著作的国际传播力建构极具现实启示意义。

“两个结合”视域下五四时期阶级斗争思想传播力建构研究

阶级斗争思想是五四时期中国进步知识分子借以确立无产阶级革命信仰并改变中国革命进程的经典理论之一。陈独秀等五四精英将阶级斗争思想作为新民主主义革命的武器进行传播时,并非机械而教条地照本宣科,而是结合农民阶级在中国革命事业中举足轻重、中国反对帝国主义压迫及大同思想等传统文化根深蒂固的实际,对阶级斗争理论进行了顺应性调适。同中国具体阶级状况的实际和大同思想的结合,有力助推了阶级斗争思想在中国空前成功的传播。五四时期阶级斗争思想传播力建构中的两个结合,对当下中国化马克思主义著作的国际传播力建构颇具现实启示意义。

地铁建设期碳排放核算研究进展

全球变暖是人们高度关注的生态环境问题之一,碳排放成为研究热点。交通运输行业会产生大量能耗,地铁作为一种安全环保的交通方式正高速建设,建筑行业又具有较大减排空间,故对地铁建设期碳排放进行核算有助于预测碳排放趋势并为碳减排提供研究基础。本研究总结了地铁建设期碳排放核算在评估方法选择、系统边界划分、清单分析等方面的研究进展,学者们多基于全生命周期理论,使用排放因子法,将碳排放来源划分为建材生产、材料运输和现场施工3个阶段开展碳排放研究。本研究就现有清单分析内容进行了对比分析,发现建材生产阶段碳排放占比最大,且钢筋、混凝土、水泥是主要的高碳排建材,依此提出了地铁建设碳排放核算的基本研究方法及减排思路。

社会主义革命和建设时期(1949—1976)中国观演建筑外部形态特征研究

在社会主义革命和建设时期(1949—1976),新中国完成了从“农业大国”到“工业大国”的历史巨变。这其中,观演建筑作为承载这一时期群众生活文化建设的物质载体,见证了其中的历史思潮发展,并直观体现在其外部形态特征上。该文拟通过文献查阅厘清全国观演建筑分布特征,并进一步从构图形式和风格特征两个方面对其外部形态特征展开研究,分析其不同形式背后的特定内涵与文化,既为当下建筑设计的多元化语境提供历史依据,也为相关部门对这一特定时期的历史建筑评价提供参考依据。

基于FBG(光纤光栅)监测技术的地铁盾构隧道环向变形研究

[目的]FBG(光纤光栅)监测技术具有动态响应快、抗干扰强、精度高、耐久性强等优点,能实现远距离实时监测,其反馈的环向变形监测数据对盾构掘进过程的参数调整有着重要意义,有必要基于光纤监测技术对管片环向变形规律进行深入研究。[方法]以某地铁隧道工程为例,采用光纤传感器对地铁隧道施工期管片进行实时监测。通过监测数据分析,研究管片施工环境中的环向应变变化规律,分析相对收敛位移与盾构掘进参数之间的相互关系。[结果及结论]监测数据表明,环向变形主要集中在管片安装之后的一周内和相邻隧道掘进的50 m范围内,当地层差且埋深小时,后掘进隧道对已施工管片收敛的影响程度为50%;当地层好且埋深大时,而后掘进隧道对已施工管片收敛的影响程度约为65%~83%。不同埋深时管片应变受土层及邻线隧道施工的影响较大,其中埋深小且土层差的管片变形变化大,埋深较大的管片约束性较好,变形变化不明显。相对收敛位移与盾构掘进参数存在明显的联系,盾构的总推力与管片的相对收敛位移存在负相关的关系,盾构的掘进速度与管片的相对收敛位移存在正相关的关系。采用FBG监测技术得到的实时监测数据,能作为盾构机掘进参数调整的依据。
