斜坡系统可靠性分析研究

:斜坡系统是一个多变的、随机的、具有多种不确定性的复杂系统 ,因此在斜坡稳定性研究中引入可靠性理论意义重大且应用前景广阔。文中从单体斜坡系统和区域斜坡系统两个方面 ,论述了斜坡系统可靠性分析的研究现状和发展趋势。单体斜坡系统可靠性研究的主要方向是 :影响因素与评价模型的进一步研究 ,初步建立可靠指标与安全系数相结合的斜坡稳定性二元指标体系。区域斜坡系统可靠性研究的主要方向是 :利用具有普适意义的可靠性指标 ,结合地理信息系统 (GIS)进行斜坡稳定性研究 ,初步建立风险评价和风险管理的斜坡安全体系

ADVANCES IN THE RESEARCH ON RELIABILITY OF SLOPE SYSTEM

Slope system is a changeable, random ,complicated system and is of manifold uncertainty, so it is necessary to introduce the reliability theory in the research on the stability of slope system which has broad prospects of application. In this paper,the present research and trends of research on slope system reliability are expounded within a single slope and regional slope system. The main trends of the research on single slope are:to study further the influence factors and to assess the model;to combine safety factor with reliability index, and to build tentatively the dualistic index system for assessing slope stability. The main trends of the research on regional slope system are:to combine GIS,to assess regional slope stability with reliability index of universal significance; to establish risk assessment and risk management,and to build tentatively slope safety system.
