摘要
结合工程实际,通过分析软土分布地区的现有桥梁下填筑路堤后,在未进行地基处理时及采用水泥搅拌桩复合地基法处理后两种情况下,路基的沉降及侧向变形、既有桩基的沉降及侧向变形,论述了地基处理可有效减少路基和路堤填筑后附近既有桩基的沉降和侧向位移,并根据分析计算结果提出既有桩基的保护措施,能够很好地指导工程设计。
Combined with the engineering practice,through the analysis of the settlement and lateral displacement of subgrade and existing pile foundation with and without cement mixing pile composite foundation treatment after embankment filling underneath the existing bridges in soft soil areas,this paper discusses that foundation treatment can effectively reduce the settlement and lateral displacement of subgrade and existing pile foundation nearby after embankment filling,and proposes some protection measures for the existing pile foundation according to the analysis and calculation of pile foundation. The results of the calculation and analysis can be quite useful and valuable for the engineering design.
