Study of influence of different distances between foundation pit and bridge pier on adjacent bridge pier
One of characteristics of city construction recent years is the increase of construction near the existing building, and the construction condition is becoming more and more complex and abnormal trend.Based on finite element numerical simulation software, Midas GTS, and the practical engineering, this paper studied the influence of different approach distance excavation to bridge pier, and the deformation characteristic of foundation pit supporting.Studies show that an adjacent bridge will have a significant impact on subsidence characteristics and mechanical behavior of the foundation pit wall;with the increasing of excavation depth, the settlement of bridge pier would increase;with approach distance decreasing, the settlement of bridge pier showed a trend of decrease after the first increase;for adjacent excavation, the effect to bridge pier can be ignored when the adjacent distance is greater than 2 times the base width, when the adjacent distance is less than 1 times the base width, the piers probably have transfinite subsidence and tilt phenomenon.
