| Abstract: | 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. |
