The Impact and Analysis of the Excavation Process of Large-scale Foundation Pit on Adjacent High-speed Railways
In order to study the importance of foundation pit excavation sequence in the construction of adjacent railway foundation pits,control the impact of foundation pit construction on the railway,and protect the safety of railway operations,this paper relies on the foundation pit of an underground garage adjacent to a high-speed railway bridge and simulated and analyzed two different excavation methods of a long foundation pit by the finite element software called Midas gts,and compared them with actual monitoring data to verify the rationality of the numerical simulation.The results show that the segmented excavation of the long foundation pit plays an important role in controlling the deformation of the adjacent railway,reducing the vertical,cross-bridge and along-bridge displacements to varying degrees.
