紧邻既有建筑深基坑支护设计及监测技术

Design and Monitoring Technology of Deep Foundation Pit Adjacent to Existing Buildings

基坑防护工程作为临时结构,不仅具有很强的区域性,且工程环境的效应复杂,其安全储备小。对于紧邻重要建筑的深基坑防护而言,在确保自身安全稳定的同时,还需控制周边建筑物的水平位移及沉降值,安全风险更高。本文详细介绍了紧邻公共建筑的深基坑防护设计、施工期间的监测、数据处理技术及针对具体问题采取的技术措施。

As a temporary structure,foundation pit protection engineering not only has strong regional characteristics,but also has complex engineering environment effects and small safety reserves.For the protection of deep foundation pits adjacent to important buildings,while ensuring their own safety and stability,it is also necessary to control the horizontal displacement and settlement value of surrounding buildings,resulting in higher safety risks.This paper introduces in detail the protection design of deep foundation pits adjacent to public buildings,monitoring during construction,data processing techniques and technical measures taken to address specific issues.
