浅析CFG桩板复合结构在高速铁路软基中的应用

摘要

CFG桩板复合结构是一种新型的软弱地基加固结构形式，逐渐在高速铁路建设中得到推广。本文结合哈大客专部分工点地基特点，通过现场大量实验数据，证明了桩板结构复合地基能有效减小地基不均匀沉降，调节桩土应力分布；重点阐述了施工工艺控制流程及质量控制要点，为客运专线软基处理提供借鉴和参考。%CFG pile plate composite structure is a new kind of soft foundation reinforcement structure, and is gradually promoted in the high speed railway construction. In this paper, combined with the foundation characteristics of Harbin-Dalian passenger dedicated railway worksite, through a large number of experimental data, it is proved that the pile composite foundation plate structure can effectively decrease the uneven settlement of foundation, and adjust pile soil stress distribution. This article mainly expounds the construction process control process and quality control points, and provides reference and reference for soft foundation treatment of passenger dedicated line.
