摘要
对于西南山区某火电厂大件设备运输道路的挡土墙进行针对性分析。在合理模拟重载效应的前提下选取典型挡土墙断面,采用有限元软件模拟重载传递到路基中,在分析填土、墙体及重载作用效应的基础上,对挡土墙的内力及稳定性进行分析。该方法不仅可以考虑土与墙体的本构关系,还可以合理地反映界面的力学效应。
Based on transport roads of heavy equipments of some thermal power plant in south-west mountainous area,this paper carries out specific analysis for retaining walls on the basis of the whole passing ability.The paper selects typical retaining wall sections on the precondition of reasonably simulating heavy load effect and adopts finite element software to simulate heavy load and transmit into roadbed,and analyzes internal force and stability of retaining walls based on analysis for fill,wall and heavy load effect.The results indicate that this method can not only consider the constitutive relationship between soil and wall,but also reasonably reflect mechanical effect of interface.
