基坑施工引起环境变形的研究方法综述

Research Methods Review of Environment Deformation Caused by Excavation

基坑工程必须以周围环境安全为前提,介绍了经验公式法、安全系数法、时空效应法、地层损失法、数值分析法等预测环境变形的方法,指出了预测基坑周围环境变形,结合多种方法,在解析解、数值解的基础上,根据前一阶段获取的实际数据反分析,修正参数后预测下一阶段的变形,才能真正做到信息化施工,保证施工的安全。

The premise of excavation must be the surrounding environment safety, empirical formula method, safety factor method, temporal effect method, ground loss method and numerical analysis method are introduced. Combining a variety of methods to predict soil deformation around ean be information construction is pointed out. The method is based on analytical solution and numerical solution, aeeording to the previous phase data, using eorrection parameter to predict the next stage of the deformation, to ensure the safety of eonstruetion.
