| Abstract: | Engineering geological features directly affect the selection of construction methods and support parameters in a project.In this paper,the water-lowering effect of sandy-pebble ground in Chengdu metro project is introduced.In addition,with analysis of the monitored data,conditions of the ground deformation and variation of the internal forces for the CD construction method and for the bench excavation method are revealed respectively.It is expected that the paper may be taken for reference to select reasonable construction scheme for other projects. |
