| 摘 要： | 武广客运专线对路基沉降要求极为严格,工后沉降不超过15 mm。桩网结构是一种能够满足加固深度超过20 m、路堤填方高度大于3 m、且能较好控制路基残余变形的结构物。通过典型工点对桩网结构在工程中的应用进行了较为系统的分析。结果表明,采用桩网结构能满足路基工后沉降不超过15 mm的要求。

| Abstract: | Wuhan-Guangzhou Passenger Dedicated Line has strict requirement on subgrade settlement,with post-construction settlement no more than 15mm.Pile net structure can satisfy reinforcement depth exceeding 20m,embankment filling height more than 3m and can better control subgrade residual deformation.This paper carries out systematic analysis on the application of pile net structure to engineering.The result shows that pile net structure can satisfy the requirement of post-construction subgrade settlement no more than 15mm. |
