软土地区路堤偏载对桥梁桩基影响分析

Analysis on the Effect of Bridge Pile Foundation under Embankment Partial Load in Certain Soft Soil Area

通过对某软土地区路堤偏载作用下城际铁路桥梁桩基计算分析,得出了桩基受力变形特征,评价了桥梁桩基的安全性。提出了增设斜桩、增加横向桩排数、设置群桩基础保护帷幕桩墙及高压旋喷桩维护墙等结构加固措施。

By calculating and analyzing the bridge piles of the intercity railway under the action of embankment partial load in soft soil area, the characteristics of the pile foundation are obtained and the safety of the pile foundation is evaluated. Suggestions have been made concerning additional structural reinforcement measures such as adding inclined piles, increasing the number of rows of transverse piles, setting group pile foundation protection curtain pile walls and high-pressure jet grouting pile maintenance walls.
