摘要
为了明确建筑垃圾再生材料填筑路基的边坡稳定性,采用规范简化Bishop法和强度折减有限元法,对天津地区常用的路基断面形式进行系统的边坡稳定性分析,结果表明:石灰掺土稳定砖料是一种很好的路基填料,上下路床均采用建筑垃圾填筑时,在非浸水条件和浸水条件下,路基高度为3 m的边坡稳定安全系数均能够满足规范要求。强度折减法和双强度折减法分析发现:边坡高度为3 m时,稳定安全系数均1.07左右。
In order to clarify the slope stability of the subgrade filled with construction waste recycled materials,this pa-per systematically analyzes the slope stability by using the standardized simplified Bishop method and the strength reduction finite element method according to the commonly used subgrade section forms in Tianjin.The analysis results show that lime mixed with soil stabilized brick is a good subgrade filler.When the upper and lower roadbeds are filled with construction waste,the safety factor of slope stability with a subgrade height of 3 m can meet the specification requirements.The strength reduction method and double strength reduction method is adopted to analyze and find that when the slope height is 3 m,the slope stability safety factor is all about 1.07.
