浅谈深基坑开挖周围地表沉降的预测方法

On the Surrounding Surface Settlement Prediction Calculation of Deep Foundation Pit

深基坑开挖是一项复杂的系统工程,在支护加固以及变形控制不当的情况下,常会因边缘地面沉降量超出设计值而危及周围各种构筑物的正常使用:如地下市政管线的破裂,周围建筑物的倾斜等。本文总结并对比基坑开挖周围地表沉降的预测方法,并提出了自己的一些看法。

Deep foundation pit excavation is a complicated project,in the event of useing improper supporting structure or deficiency of deformation control,the surrounding surface settlement may be outside its province,which will affect normal service of other constructions,such as municipal pipeline rupture and building inclination.This paper summarizes and compares the theories of the surrounding surface settlement prediction calculation of deep foundation pit,and gives out self views.
