深基坑支护结构变形预报

Prediction for Structure Displacement of Deep Foundation Pit

通过现场量测的深基坑围护结构变形信息资料,结合参数优化反分析技术及弹性地基梁有限元计算,建立了深基坑开挖中支护结构变形的预报方法。该方法可对深基坑开挖中支护结构变形做出评估,指导施工。

In this paper, an approach for predicting the displacement of the retaining structure of foundation pit is established by gathering the information in - place and optimum back analysis method and elastic foundation finite element analysis.By this approach,the method for calculating displacement of the retaining structure in excavation can be estimated,and thererore the construction process can be conducted successfully.
