摘要
Based on the deep foundation pit project of Hua-Fu in Shenyang, study of road traffic loads under the stability of deep foundation pit bracing structure, after many times numerical simulation of foundation pit with ADINA, the relationship between parameters and deformation of supporting structures are summed up by changing relevant parameters of foundation pit and supporting structure. And through compared with actual data, got a series of conclusion, found in urban road traffic loads, the main influence factors for the operation of traffic generated by static load (include vehicle weight, the distance from the foundation pit road traffic) and vibration dynamic load and produce their own features of the foundation pit itself influence. It can offer reference to optimization of foundation pit supporting structural scheme.
