土质路基双块式无砟轨道参数影响分析

Analysis of parameters influence of soil roadbed double block unballasted track

针对土质路基双块式无砟轨道结构,建立了双块式无砟轨道整体有限元模型,研究了主要参数变化对无砟轨道受力的影响,确定了无砟轨道设计参数,从而确保无砟轨道结构设计的安全性、经济性。

Aiming at soil roadbed double block unballasted track structure, the general finite element model of double block unballasted track was built, the main parameters change influences on unballasted track stress was studied, the unballasted track design parameters were deter- mined, therefore guaranteed unballasted track structure design safety and economic.
