广州某周围复杂环境的深基坑支护案例分析

对广州市市区某医院门诊综合大楼的深基坑支护工程进行了分析。考虑到基坑周围环境复杂，工程师在不同的部位分别采用了人工挖孔桩、高压旋喷桩、双层内支撑及喷锚的联合支护方式作为该工程深基坑护壁。这一设计有效保护了深基坑并保证了其周边构筑物的安全使用。通过对该项目的分析，为周围复杂环境的建筑物深基坑设计提供了一定的参考。

Study of Protecting a Deep Foundation Pit in Guangzhou against Complicated Surrounding Environment

This article studies the deep foundation pit protection of an outpatient hospital building located in Guangzhou city. Considering the complicated environment surrounding the foundation pit, engineers who conducted the design combined hand-dug piles, jet piles, double-loop systems and spray anchors at different locations to support the pit wall. This design effectively protects the deep foundation pit and also secures the use of its adjacent structures. The purpose of this study is to provide reference for the design of deep foundation pits that are subjected to complicated surrounding environment.
