弃土堆载的位置对邻近桩柱式桥墩受力影响分析
Analysis on the Influence of the Position of the Dump Loading on the Force on the Adjacent Pile Pier
摘要
Abstract
A viaduct with a large amount of abandoned soil left in the vicinity experienced girder misalignment,block extrusion cracking,and cracking and dislocation of the piers and columns.In order to study the influence of the position of the dump loading on the forces on the adjacent pile piers,this paper considers four positional scenarios,and uses Plaxis 3D to build a three-dimensional finite element model for the viaduct to study the laws of the horizontal displacement of the pier body to the bridge,the horizontal displacement of the foundation pile to the bridge,and the bending moment of the foundation piles in relation to the location of the dump loading in different transverse directions.关键词
