摘要
以一般地区衡重式路肩挡土墙为例,文章按照荷载分项系数法和总安全系数法对不同墙高、不同填料和基底岩土参数的挡土墙进行了大量计算,分析了不同计算方法和不同挡墙设计参数对墙身截面积的影响,所得结论及大量计算结果,为今后《公路路基设计规范》的修订提供一些基础资料,同时,也可为铁路路基挡土墙采用极限状态法设计提供借鉴。
Taking the commonly-used balance weight shoulder quantity of calculation on retaining walls of different height, retaining wall for example, this paper carries out a great filling and geotechnical parameters with methods of partial coefficient and general safety factor, and analyzes the effect of different calculation methods and different retailing wall design parameters on wall. The result is expected to offer reference for designers and provides basic data for the future revision of Code for Design of Highway Subgrade.
