复杂环境条件下深基坑支护方案设计研究

Study on the Design of Deep Foundation Pit Supporting Scheme in Complicated Environment

根据工程地质和水文地质条件特点并结合工程周边的环境情况,对处在复杂环境条件下的浙江建设科技研发中心项目深基坑支护方案进行了研究,介绍了采用地下连续墙加内支撑的方式进行基坑支护的技术。并通过深基坑支护结构设计软件对其进行计算分析,为类似深基坑的设计提供参考。

Based on the characteristics of engineering geology and hydrogeology conditions and according to the surrounding environment, the study was carried out on a deep foundation pit supporting scheme which was under complicated environ- mental conditions. The paper introduces the supporting technology for foundation pit with diaphragm wall and inner bracing; and the calculation was made by the design software of deep foundation pit supporting structure to provide reference for the similar deep excavation construction.
