Analysis of influence of road and canal construction on pile foundation of rail transit viaduct
With the rapid development of urban construction in modern society,the construction projects around the pile foundation of urban rail transit viaduct are more and more complicated,so the analysis of the influence of surrounding construction on the pile foundation of viaduct is more and more important.This paper takes an example of the influence of the road reconstruction project from Ke Cun to Guomao Avenue and the connecting project of Ke Cun canal system on the access line of Guantang parking lot of JIN-YI-DONG Urban rail Transit project.Midas GTS is used to conduct finite element numerical analysis to study the pile foundation,displacement and settlement changes of rail transit viaduct before,during and after the construction of canal engineering.The results of model calculation show that the displacement and settlement of piles will be caused by the construction of roads and canals,and the influence results will decrease with the increase of the horizontal projection of the two piles.It can provide a useful reference for the pile foundation construction projects of other adjacent rail transit viaduct in Yiwu area.
