【摘要】 土坡稳定性分析是岩土工程中的一个热门课题。在土木工程中,边坡稳定分析十分重要,如各种各样的天然边坡、高速公路、机场、填埋场、土石坝工程、各种填方、挖方工程等等都需要进行稳定分析。滑坡往往又伴随着地震、暴雨发生,并引发泥石流等严重的自然灾害。 本文首先分析了各种因素对边坡稳定性的影响。通过应用目前研究较多的极限平衡法和有限单元法,结合简单边坡和复杂边坡进行稳定性计算,介绍了此两种方法的原理、现状和发展,总结了各自的优缺点和存在的问题。 本文结合富阳来龙山滑坡的工程实例,介绍了来龙山滑坡的概况,分析了滑坡产生的成因、滑坡要素及监测情况,并用极限平衡法和有限元法分别进行了安全系数的计算与分析,提出并验证了自己的观点。 本文的工作主要是对极限平衡法和有限单元法在边坡稳定性计算与研究中的应用进行分析和比较。
【Abstract】 Analysis of slope stability is one of the most important problems in Geotechnical Engineering. The stability of all kinds of natural slope, higeway, airport, refuse dump, dam, fill, excavation need to be analysed .Firstly, the simple slope either with the two-layered or three-layered soils were calculated with softwares based on limited equilibrium method and the finite element method. The principle,current situation and development of these two methods were introduced. And advantages and shortcomings of the two methods were summarized .Secondly, the Fu Yang Lailong Mountain slope failure was introduced. The factors influcing the slope stability were analysed and the calculated results were compared with those obtained by insitu monitoring.Finally, some conclutions were obtained, which are important to engineering application.
