摘要
通过对南京地铁明挖段基坑工程变形情况进行分析,指出狭长条形基坑的变形特征,并分析不均匀超载、降水、地表刚度、开挖范围及开挖时间对基坑变形的影响规律,提出相应的控制基坑变形的工程措施。
By analyzing deformation of foundation pit of cut - and - cover zone in Nanjing metro, the characteristics of the deformation of slim foundation pit are described. The deformation principles of the foundation pit due to unsymmetrical load, dewatering, ground surface stiffness, digging range and time are analyzed. The engineering measures against the deformation of foundation pit are put forward.
