复杂地理环境下深基坑的设计与施工技术

Design and Construction Technology of Deep Foundation Pit Under Complex Geographical Environment

结合某工程案例主要分析如何开展复杂地理环境下的深基坑设计和施工工作。重点分析了基坑支护设计、锚索桩及止水帷幕设计、咬合桩设计;阐述了成井、支撑体系、土方开挖以及监控量测施工内容,最终发现基坑设计及施工对周边建筑物的影响较小,达到施工基本要求。

This paper mainly analyzes how to carry out related design and construction work of deep foundation pit in complex geographical environment in combination with a project case.The design of foundation pit support,anchor cable pile,water curtain and occluding pile are analyzed.The well completion,support system,earthwork excavation and monitoring and measuring construction contents are expounded.Finally,it is found that the design and construction of foundation pit have little influence on the surrounding buildings and meet the basic requirements of construction.
