Economic Analysis of Deep Foundation Pit Support Scheme
In order to study the engineering cost of different supporting schemes for the foundation pit of rail transit,based on the civil construction project of kunming rail transit line 5,based on the factor of safety analysis,time limit analysis and cost analysis of the two construction schemes of diaphragm wall heightening and steel sheet pile support,the research results show that,the steel sheet pile bracing scheme has higher factor of safety,shorter construction period and lower cost,which can be used for reference for the foundation pit bracing scheme of similar projects.
