摘要
为了研究深基坑工程以变形控制为主的设计方式,基于Biot理论,结合南京珠江路地铁站基坑工程实例,采用非稳定渗流-应力耦合的方法对基坑降水开挖过程中的变形问题进行分析,计算出坑底开挖面的隆起量和桩后地表沉降,得到深基坑开挖及降水过程中的变形规律。经比较,计算结果与实测值基本一致。
In order to research the design method of deep foundation pit controlled by deformation,on the basis of Biot＇s theory,combined with the deep foundation pit of Nanjing ZhuJiang Road underground station,with the method of unsteady seepage field coupled with stress field,this paper analyses the deformation of deep foundation pit during the dewatering and excavation,figures out the excavated work face uplift amount and the ground sedimentation back of piles,obtains the law of deep foundation pit deformation in the process of dewatering and excavation.By comparison,the computed values are in conformity with the measured values.
