高速铁路刚柔性桩复合地基沉降影响分析

刚柔性桩复合地基是一种新型的地基处理技术,在高速铁路工程中的应用较少。分析其适用范围和工作机理,着重利用有限元法分析垫层模量、垫层厚度、刚性桩长度和路基填筑高度等对刚柔性桩复合地基沉降所产生的影响及规律,旨在为以后该类型高速铁路复合地基沉降量的设计和控制提供参考。

Influence on Settlement of Rigid-Flexible Pile Composite Foundation of High Speed Railway

Rigidflexible pile composite foundation is a new foundation treatment technology, the application of which in high speed railway engineering is less. Its applicable scope and working mechanism are analyzed. The paper focuses on using finite element method to analyze the influence of cushion thickness, cushion modulus, rigid pile＇s length and the height of embankment on the settlement of filling on rigidflexible pile composite foun dation and the rules, in order to provide reference to the design and control settlement of this type of composite foundation of high speed railway.
