深基坑支护设计及对周边环境的影响分析

Analysis of influence of deep foundation pit support design on surrounding environment

以深圳市某深基坑支护工程为例,结合工程概况、地质情况和周边环境,分别从自身因素和环境因素两个角度对可能出现的风险进行了分析与评估,并根据工程实际情况,对支护方案进行了比选,采用理正深基坑软件进行了不同工况下的模拟分析,与现场实测地表沉降、管线沉降及建筑沉降等监测数据进行对比分析,验证了该深基坑支护方案的可靠性与安全性,为此类工程提供参考与借鉴。

Taking a deep foundation pit support project in Shenzhen as an example, combined with the project overview,geological conditions and surrounding environment, the possible risks were analyzed and evaluated from the perspectives of its own factors and environmental factors, and according to the actual situation of the project, The Lizheng deep foundation pit was used for simulation analysis under different working conditions, and compared and analyzed with on-site monitoring data such as ground settlement, pipeline settlement and building settlement, which verified the reliability and safety of the deep foundation pit support scheme. Provide reference and reference for such projects.
