随着上海城市轨道交通网络建设的发展,超深基坑已相当普遍。由于地质情况复杂,施工场地受限等工程制约因素增多,工程周边环境保护以及工程耐久性的要求提高,工程风险点的增加,都使工程的实施难度不断增大,也对工程建设提出了新的更高要求。对上海城市轨道交通的超深基坑所遇到的工程技术与管理问题作了总结和回顾,介绍了上海在这些方面的经验,并探讨了上海超常规的城市轨道交通网络建设将会遇到的超深基坑工程技术和管理难题及其解决对策。
With the development of urban rail transit network construction in Shanghai, ultra-deep foundation pit has been quite common. Due to complicated geological conditions, limited construction sites and other engineering constraints increased, environmental protection projects surrounding the project and the durability requirements increase, the project risk points increase, make the project more difficult to implement, but also the construction of a new The higher requirements. Summarized and reviewed the engineering technology and management problems encountered in ultra-deep foundation pit of Shanghai urban rail transit, introduced Shanghai’s experience in these aspects and discussed that Shanghai’s unconventional urban rail transit network construction will encounter Ultra Deep Foundation Engineering and Management Problems and Solutions.
