Deformation Pattern of Foundation Pit Excavation beside Silt Soil Railway Subgrade

Abstract:

Foundation pit excavation beside silt soil railway subgrade in the water net plain district is influenced by overload of backfilled roadbed, train's vibrating load and high groundwater level, so foundation pit instability occurs easily. Numerical simulation is done on several parameters such as different depths of pit cutting, distances from subgrade, speeds of the train, and so on. Through analyzing changes and impact ranges of the pore pressure and displacement under various work conditions, it reveals lateral deformation mechanism of the foundation pit. And also it provides references for supporting design of foundation pit beside silt soil subgrade.
