摘要
为解决衡重式挡土墙自重大、基底应力扩散较差的问题,文中以江西省东北部某山区公路改造项目为例,综合考虑挡土墙施工过程容易出现的倾倒变形、基底不均匀沉降等问题,对衡重式挡土墙进行优化设计,并对工后衡重式挡土墙基底土压力进行监测.结果表明,各监测点基底土压力增加幅度约为3.0 kPa/月,衡重式挡土墙投入使用期间基底土压力变化幅度较小,证明了挡土墙的耐久性和稳定性.
Abstract
In order to solve the problems of self-weight and poor basement stress diffusion of counterweight retaining wall,based on a road re-construction project in a mountainous area in northeast Jiangxi Province,this paper comprehensively considers the problems such as tipping de-formation and uneven basement settlement that are prone to occur during the construction of the counterweight retaining wall,optimize the de-sign and construction of the counterweight retaining wall,and monitor the subsoil pressure of the counterweight retaining wall foundation after construction.The results show that the increase of basement earth pressure at each monitoring point is about 3.0 kPa/month,indicating that the change of basement earth pressure during the operation of the counterweight retaining wall is small,which verifies the durability and stabili-ty of the retaining wall.
