Abstract

The settlement and deformation caused by structural self-weight during the construction of pump station located on soft ground along the rivers is a key consideration in water transportation engineering. This study focuses on a newly built large-scale flood control and drainage pump station along the Yangtze River. Basic physical and mechanical property tests are conducted on representative soil layers at different depths through on-site sampling. Large-scale finite element software is used to build a 3D model of the pump station to simulate the structural force, settlement and deformation of the pump station treated with bored piles of varying lengths. The finite element calculation results showed that the bored pile foundation improvement scheme can effectively control the settlement deformation and the maximum uneven deformation between structural joints. The maximum Mises stress values are less than 10 MPa at typical locations, such as pump house section along the end of the water flow direction, track beams, gate piers, base plates, diversion piers, and other structures. The study indicates that bored pile foundation treatment on waterfront sedimentary soft ground could effectively control settlement, deformation, and structural stress concentration.
