| 摘 要： | 根据深基坑支挡结构水平位移监测信息,应用灰色系统的原理和方法,对基坑的变形发展变化进行预测是一种有效手段,对深基坑工程的设计和施工具有非常重要的意义。预测中灰色模型的建立以等时距原始数据为前提,结合苏州某地铁车站的基坑开挖工程,通过灰色理论中的GM(1,1)模型对基坑开挖所引起的支挡结构的水平位移进行了预测,其预测结果与监测结果接近。结果表明,在GM(1,1)模型中,利用初期水平位移实测值来预测未来一定时间内的支挡结构的水平位移值能够获得比较准确的预测结果,并且其预测模型可以应用于动态设计和信息化施工。

| Abstract: | By the lateral displacement monitoring information of deep foundation pit,the grey system theory can be applied to forecast the unknown displacement of deep foundation pit.It is very important for designing and constructing of deep foundation pit.The grey model is based on the equal interval original data .A subway station in Suzhou excavation engineering,the horizontal displacement of retaining structures caused by excavation is predicted through GM(1,1) model of the gray theory,and the predicted data is c... |
