Series of centrifuge shaking table tests study on seismic response of subway station structures in soft soil sites

open access: yesUnderground Space
Due to the planning of the subway route, it is difficult to avoid crossing soft soil site conditions at subway stations. The seismic response of subway station structures is closely related to the surrounding soil site.

Dynamic Responses of RC Underground Subway Station and Soil during the Strong Earthquake

open access: yes, 2011
Underground subway RC structures suffered significant damage during many earthquakes, so it is important to study the seismic behavior on RC subway structure. The shaking table model test is made of the Beijing typical subway station structure.

Research on Seismic Performance of a Two-Story, Two-Span Underground Subway Station with Split Columns Based on the Quasi-Static Method

open access: yesApplied Sciences
The behavior of center columns in shallow-buried underground subway station structures resembles that of high-rise buildings. In both cases, these columns experience significant vertical loads during earthquake events and are susceptible to brittle ...

Cracking Analysis of Roof in Subway Station Under Construction and Application of “Alternative Bay Construction Method” [PDF]

open access: yes, 2017
改革开放以来,我国地铁建设事业获得迅猛发展。地铁建设过程中经常出现车站主体结构开裂问题,特别是在顶板位置。一般情况下,地铁车站结构顶板长度可达150m以上,厚度为500~1000mm,为超长大体积混凝土板,且其受到侧墙、框架柱及周边土体等的约束较大。在施工过程中,顶板结构在温度和收缩共同作用下容易产生开裂问题。 本文以厦门地铁二号线“新阳大道站”结构顶板“跳仓法”施工为工程背景,分析了地铁车站结构顶板在不同工况条件下的温度场及应力状态特征,进而判断结构是否存在开裂风险。文章内容主要包括: 1 ...
