摘要:深基坑工程是一个非常复杂的岩土工程问题，涉及到土层性质、支护结构、地下水及周边环境等，深基坑支护方案选择的合理性直接影响支护结构的安全性、经济性、工期等。在深基坑支护设计中，应结合场地情况及周边环境特点，创新性的选择支护型式，既能解决实际工程问题又各方面的比较都较优。现以某深基坑支护设计方案进行论述，通过设计计算、施工、变形监测及经济等方面进行比较分析，多指标下考察分析采用灌注桩及管桩支护的综合效益，对后续类似工程会起到积极的指导和借鉴意义。
Abstract: Deep foundation pit engineering involves complicated geotechnical engineering problems, including the soil properties, supporting structure, groundwater and the surrounding environment. The rationality of the supporting scheme of deep foundation pit directly affects the safety, economy and construction schedule of the supporting structure. The design of deep foundation pit support should consider the site conditions and surrounding environment characteristics. The innovative support is able to solve practical engineering problems, as well as possessing comparative advantages of all aspects. This paper discusses the design scheme of a deep foundation pit support, compares and analyzes the comprehensive benefits of using cast-in-place piles and pipe piles under multi-index through design calculation, construction, deformation monitoring and economic analysis, which is of positive reference significance for similar projects.
