【摘要】 为解决由煤矸石和黄土分层压实而形成的复合介质高陡边坡的稳定性问题,在分析边坡稳定影响因素的基础上,建立了植物根系加固边坡表层土体的力学模型,并推导出植物根系对提高土体力学性能的贡献。最后应用FALC软件对1#拦渣坝边坡的稳定性进行了全面分析模拟,认为该边坡在一定的条件下会发生滑坡,建议采用深层和表层相结合加固的方法对边坡进行处理。结果表明该方法实用有效,能够保证边坡的稳定性,为改善同类边坡的周围环境和最终有效的治理提供了实践经验。更多还原

【Abstract】 In order to research the stability of high and steep composite medium slop consisting of loess and coal wastes layer by layer,on the basis of analyzing the factors affecting the stability,the mechanics model for the roots of plant reinforcing surface soil of slope was built.The contribution of the roots of plant to the improvement of mechanical property of soil was deduced.A numerical simulation was made on the stability of slope of some debris retaining dam using FLAC software.It was pointed out that the slope will slide under certain condition.It was suggested that the measure of surface layer reinforcing combined with deep layer reinforcing should be took to the slope.The result show that the measure is practical and effective,can ensure the stability of the slope.It provides practical experience for the improvement of mechanics surroundings of similar slope and its effective treatment.更多还原
