| 摘 要： | 在软土地区邻近既有隧道进行深基坑设计，如何减小开挖卸载对隧道产生的影响显得尤为重要，结合上海外滩通道项目邻近隧道的一段基坑工程，运用有限元方法对不同的方案进行了数值计算比较，提出了深浅坑设计方案，为优化基坑设计和施工提供了有益的参考。

| Abstract: | It is absolutely important to reduce the influence of excavation to Adjacent tunnel when a deep foundation pit is designed in soft soil area. According to one foundation pit engineering of the Waitan passage in Shanghai, manerical simulation of different schemes are compared using finite element analysis method in this paper. A high-low pit design method is proposed to be referenced for foundation pit design and construction of similar engineering project. |
