摘要
2010年上海有两个与基坑设计相关的规范进行了新旧更替。基于地铁车站基坑设计,从规范的适用性、规范的衔接、地铁基坑等级划分的演变和基坑稳定性验算等几个方面,探讨了目前各种规范之间的关系以及设计实践中的规范选用。对环境良好的地铁基坑变形控制和新规范未予明确的稳定性验算安全等级进行了分析讨论,提出了应用建议。
In 2010, two subway engineering codes related to excavation design replaced the old ones. From the point of subway station excavation design viewpoint, this paper stud- ies the relationship between the present codes and the ap- plications of the old and the new ones, analyzes the deform- ation control of subway station excavation on condition that there are no any important structures or pipes to protect nearby, and the safety level in stability evaluation which is not yet specifically defined in the new codes.
