| 摘 要： | 在基坑开挖施工过程中,随着基坑挖深和降水量的增加,常常引起基坑周边地面缓慢地沉降。本文以灰色理论为基础,提出了基坑周边地面沉降预测与分析的一种新方法,并建立了不等时距GM(1,1)沉降预测模型进行计算与工程实测值比较,验证了灰色理论在基坑周边地面沉降预测分析中的可行性、有效性。

| Abstract: | In the course of excavating construction in the foundation pit,dig with it dark with increase of precipitation,often causes the peripheral ground of the foundation pit to slowly subside.This text is based on grey theory,a new method that it have put forward the peripheral surface subsidence of foundation pit and predict and analyze,set up unequal time interval model of predicting from GM(1,1),calculate compared with surveying value of project,predict the feasibility,validity in analyzing in the peripheral g... |
