摘要
码砌是填石路基较为常用的边坡形式,目前设计规范对于码砌厚度要求偏高,在填石路基实际施工中往往达不到要求。本文采用力学计算与有限元模拟分析相结合的方法对路堤稳定性进行研究,结合调研已通车多年的任寨路、水南路及刚通车的六宜路等路段填石路堤码砌边坡薄层码砌的使用情况,提出填填石路堤填边坡进行50 cm的薄层码砌即可满足稳定性要求。
Slope of manual build is commonly used in Stone-filled subgrade,the requirement of the thickness of manual build in design is too thick at present,which cannot be reached in constraction. The method of combinding mechanical calculation and finite element analysis is used on the study on stability of stone-filled subgrade in this article,with the addition of the fine application effection of thin-build stone slope in real project surveying at Shuiren-Luzhai roud,Shuiren-Nanning roud opened to traffic many years and Liuzhain-Yizhou roud opened to traffic recently. Then,50 cm of thin-build stone slope being enough to the stability of stone-filled subgrade is presented.
