基于传递矩阵法的重载铁路路基加筋水泥土排桩结构应力及变形分析

Structure Stress and Deformation Analysis on Subgrade Reinforced Cement-Soil Pile of Heavy Haul Railway Based on Transfer Matrix Method

通过将重载铁路路基加筋水泥土桩结构体系视为路基土—水泥土—路基土的三层层状结构体系,提出一种具有创新性的计算方法,并将传递矩阵法应用于计算重载铁路路基加筋水泥土桩结构体系的应力和变形等问题,同时运用有限元软件进行分析,将两种结果进行对比,发现对比结果较为吻合。

The heavy haul railway subgrad e reinforced cement- soil pile structure is considered as subgrade soil-cement soil-subgrade soil structure of three layer system, and stress and deformation calculation method of heavy haul railway subgrade reinforced cement soil pile structure system based on transfer matrix is proposed. By comparison with the finite element method, the calculation results are in good coincidence with finite element method＇s.
