边坡稳定性的确定性和非确定性分析方法发展

Development of Deterministic and Non-deterministic Analysis Methods for Slope Stability

影响边坡稳定性的因素存在确定性和非确定性,目前所提出的多种分析评价方法都有各自的特点和适用性。为了便于对工程中边坡的稳定性进行合理评价,快速而准确地选择出合适的方法,按照分析因素确定性程度对几种比较经典且常用的边坡评价方法就其原理、条件、适用类型等进行分析。与边坡稳定性相关的因子众多,且相互联系、彼此作用,不同类型条件边坡的主要稳定性影响因子存在差别,在采用非确定评价方法进行评价前,需要更加仔细地挖掘适合待评价对象的影响因子。将确定性和非确定性方法进行耦合,则可以实现优势结合,从而更准确地解决问题。

There are deterministic and non-deterministic factors affecting slope stability.At present,various analysis and evaluation methods have their own characteristics and applicability.In order to facilitate the reasonable evaluation of the stability of the slope in the project and select the appropriate method quickly and accurately,this paper analyzes the principles,conditions and applicable types of several classical and commonly used slope evaluation methods according to the degree of certainty of the analysis factors.There are many factors related to slope stability,which are interrelated and interact with each other.The main stability influencing factors of slopes under different types of conditions are different.Before using the uncertain evaluation method to evaluate,it is necessary to excavate the influence factors suitable for the object to be evaluated more carefully.Coupling deterministic and non-deterministic methods can achieve a combination of advantages,so as to solve problems more accurately.
