| 摘 要： | 上海地铁二号线西延伸工程威宁路站主要穿过无自稳能力的淤泥质地层,其拟建的3、4号出入口通道采用浅埋暗挖法管幕预支护施工。采用有限元数值方法对其施工效应进行了分析。分析结果认为，施工过程洞室稳定，浅埋暗挖管幕预支护施工方法可行，地表变位满足城市环境要求。

| Abstract: | Weininglu Station, which is a part of the West-Extension Project of Subway Line 2 in Shanghai, passes through the silty stratum of very poor stability, and Passageway No. 3 and No. 4 adopted pipe pre-support and deep - hole grouting in working face. Based on the construction technology of Passageway No.3, the construction effect is analyzed using finite element numerical method. The results show that the tunnel is steady during construction and surface displacement meets the demand of the city environment. |
