| 摘 要： | 城市基坑工程面临周围环境条件复杂、支护结构形式多样化、周边地下工程资料档案不完整等问题。北京西城区某基坑工程因存在上述问题,实际完成方案较原始设计方案有较大变化。通过介绍该工程的设计和施工情况,并结合实测资料,对该工程的3种情况(原始方案理想施工条件、原始方案实际施工条件和实际完成方案)进行了有限元数值计算及比较。对于此类基坑工程,设计和施工的相互配合和协调非常重要,而且必须高度重视地下工程资料的规范化和管理。

| Abstract: | Deep excavation in a city faces the strict environmental demands and unconventional excavated sections.And the files for the underground of the surroundings are often absent.A case study in Beijing is introduced.During excavation,the retaining structure was modified two times based on the original design and construction conditions.Three schemes of the retaining structure are calculated by plane finite element method.The monitoring records of horizontal deformation are compared with the results of FEM.It is emphasized that more attention should be paid to the files of the underground engineering.Meanwhile,the design of the retaining structure must be corresponded with the surroundings of the construction. |
