Translation of Metro Station Names in Guangzhou and Foshan from the Perspective of Symbolic Function of Translation Landscape

Guangzhou and Foshan enjoy relatively mature metro network.However,some names of metro stations are over-transliterated in Pinyin.Such a translation method is used in translating general names,nouns of locality and some names of tourist destinations.With translation landscape and linguistic landscape theories,the reasons and impacts of over-transliteration in Guangzhou and Foshan metro will be discussed from the perspective of symbolic function.English names of Metro stations in other cities serve as a reference so as to appropriate solutions.

Risk identification and risk mitigation during metro station construction by enlarging shield tunnel combined with cut-and-cover method

Constructing a metro station by enlarging shield tunnels combined with a mining/cut-and-cover method provides a new method to solve the contradictions of construction time limits of shield tunnels and stations. As a new-style construction method, there are several specific risks involved in the construction process. Based on the test section of Sanyuanqiao station on Beijing metro line 10, and combined with the existing methods of risk identification at present, including a review of world-wide operational experience of similar projects, the study of generic guidance on hazards associated with the type of work being undertaken, and discussions with qualified and experienced staff from the project team, etc., the specific risks during the construction process of the metro station constructed by enlarging shield tunnels combined with the cut-and-cover method are identified. The results show that the specific risks mainly come from three construction processes which include constructing upper enclosure structures, excavating the soil between shield tunnels and demolishing shield segments. Then relevant risk mitigation measures are put forward. The results can provide references for scheme improvement and a comprehensive risk assessment of the new-style construction method.

Analysis of the Development of the Commercial Space Around Metro Stations in Urban Core Areas Based on Place Making: A Case Study of Chunxi Road Metro Station in Chengdu

The metro is the most efficient and convenient public transport system in modern cities. For urban core areas in China, in which the metro was built later, there was more consideration for meeting the traffic needs of cities. However, there are few studies of collaborative planning for metro stations and their surrounding space. Thus, there is an urgent need to conduct research on collaborative planning for metro stations and their surrounding commercial space in urban core areas. Unlike conventional methods of integrated design of stations and cities, this paper, based on the theory of place spirit, took Chunxi Road Metro Station in Chengdu and its surrounding commercial space for example. It explored the pattern and characteristics of the place in the commercial space around the metro station, analyzed the strategies of cultural and commercial integration, as well as architecture, street, landscape and other aspects of the design method in the space, and explored the strategies of place-making and infiltration, providing a reference point for the development and place-making of the commercial space around metro stations in urban core areas.

Cluster and characteristic analysis of Shanghai metro stations based on metro card and land-use data

Metro is an important form of public transport in Shanghai.Based on the metro card data,we conduct the cluster analysis of Shanghai metro stations according to the pattern of passenger flow changing with time.Then the characteristics of travel time and surrounding land use are investigated for different types of stations to explore the relationship between urban land-use characteristics and travel activities reflected by passenger flow at metro stations.It is found that the passenger flow pattern of metro stations is closely related to the location conditions of stations and its surrounding land-use patterns.Based on various characteristics,285 metro stations are classified into four types,including residential-oriented stations,employmentoriented stations,employment-residence-oriented stations,and integrated functionaloriented stations,reflecting the interaction between spontaneous travel behavior and urban land-use characteristics and providing a reference for optimizing the urban functional structure and the spatial allocation of facilities.

黄土地区洞桩法地铁车站边桩和中柱的受力变形机理

[目的]为了确保黄土地区洞桩法车站施工过程中重要竖向承重构件的稳定性,需要对施工过程中边桩和中柱的受力变形机理进行研究,并对最不利受力阶段边桩和中柱提出变形控制措施。[方法]以西安地铁2号线何家营站为研究背景,通过数值模拟与现场监测的方法,对施工过程中边桩的水平位移、钢筋内力、水平土压力及中柱应变展开研究。[结果及结论]扣拱施作以及站厅层和站台层土体开挖是边桩水平位移最不利的三个阶段,在这些关键阶段施工时,应在结构内部架设钢支撑并适当加固已扰动的地层;在桩梁和扣拱施作中,边桩主筋承受轴向压力,而在站内剩余土方施工阶段,边桩背土侧的钢筋由轴向压力逐渐转化为轴向拉力,且随着边桩埋深的增大,钢筋的轴向拉压力增长变缓;在扣拱初期支护施作中,土压力在边桩埋深6.6 m处达到最大值34.5 kPa,且随着边桩埋置深度增大,边桩的桩侧压力增长速率显著,因此车站内侧的土方开挖是控制边桩迎土侧土压力大小的关键阶段,必要时对桩后土体进行注浆加固有利于提高桩基的承载力;中跨扣拱施工时,中柱的应变呈现出先减小、后增大的趋势。

考虑洪水入侵的地铁站楼梯疏散风险研究

为增强地铁站应对洪涝灾害能力和楼梯设计韧性,基于改进的k-ε模型和洪涝疏散风险评价模型,构建地铁站楼梯上洪水入侵流态数值仿真场景,定量分析坡梯设置、楼梯倾斜度和洪水深度对洪涝疏散风险的影响。研究结果表明:在相同倾斜度(23.2°)和入侵洪水水深(0.3 m)的情况下,相较于楼梯台阶对洪水的阻缓作用,斜坡上洪水流速更快、水深更为平稳,但斜坡具有更高的洪涝疏散风险;洪涝疏散风险与楼梯倾斜度成正相关,疏散风险随着楼梯台阶的降低呈现“前快后缓”特征,斜坡对疏散风险的边际影响更为均匀,而宽大的台阶设置更有利于缓解疏散风险;楼梯上平台入口水深越大,洪涝疏散风险越高;洪水与下平台积水容易产生跳水现象,导致洪涝疏散风险急剧攀升和震荡递减。研究结果可为地铁站科学制定洪涝疏散方案和楼梯设计提供理论指导和管理启示。

南京地铁7号线中胜站密贴下穿运营站MJS+水平冻结施工与实测研究

为解决南京新建地铁7号线在承压富水砂层近贴下穿既有10号线中胜站开挖时易发生涌砂涌水现象及冻结对既有线变形的影响问题,提出一种全方位高压喷射工法(metro jet system,MJS)+水平冻结法联合加固承压富水砂性地层的施工方法。根据实际工程,确定MJS+水平冻结加固工艺、加固参数、加固范围及冻结的方案,并通过数值模拟方法预测冻结温度场的变化规律、计算开始冻结的合理时间和积极冻结时间。对冻结过程中的土体温度、冻结及开挖过程中的既有车站底板位移进行监测,并在此基础上对暗挖方案进行优化。工程实践表明:1)冻结过程中中部MJS加固体温度一直高于端部MJS加固体温度,应当加强对中部位置温度的监测;2)冻土帷幕范围应控制在MJS加固体范围内,否则土体冻结会对冻胀变形影响较大,为此提出了上部钻孔取土泄压及间歇冻结的方案,可在一定程度上减小冻胀;3)本工程冻结及开挖阶段既有车站结构变形较小,减小了对近贴既有车站结构的影响;4)优化后的暗挖方案可加快施工进度,原开挖时间约80 d,优化后开挖时间缩短至66 d。
