Analysis On Stability Of Deep Foundation Pit Supporting Structure Under Traffic Loads And Buildings

With the development of urban construction and industrialization, theproject of foundation pit goes into large scale and depth. Meanwhile, it is generallysurrounded by dense buildings. The working space is very narrow and there are alwayssome tall buildings and public service which must be protected. Therefore, there is a highrequirement of the stability of foundation pit and the control of displacement. Based onthe deep foundation pit project of Asian Finance Building in Shenyang, study ofsurrounding buildings and road traffic loads under the stability of deep foundation pitbracing structure， after many times numerical simulation of foundation pit withMIDAS/GTS, the relationship between parameters and deformation of supportingstructures are summed up by changing the vehicle load and the distance from thebuilding and the static and dynamic traffic loads. It can offer reference to optimization offoundation pit supporting structural scheme.
