相邻不对称超深基坑支护设计探讨

Design of supports for adjoin asymmetric extra-deep foundation pit

相邻两工程(A、B工程)地处福建省泉州市丰泽区东海片区,场地位于泉州湾海岸带上。A工程设置3层地下室,B工程设置4.5层地下室,两基坑同时施工作业带来相应问题。文章详细介绍了相邻两基坑工程概况和特点、支护体系、设计解决方案、不对称开挖条件下的有限元计算结果、基坑现场监测等内容。

The two deep foundation pit is located in Fujian Province of Quanzhou City and is on Quanzhou Bay coastal zone. A project set up3-storey basement,B project is provided with 4. 5 basement. This paper introduces the general situation and characteristics of foundation pit engineering,the supporting measures and design scheme,the calculation of internal force deformation under asymmetric excavation conditions,the construction of foundation pit and the field monitoring.
