Monte Carlo Numerical Simulation Of The Reliability Of Slope Stability And Its Application

In geological engineering, it is a very important problem that the stability analysis of slope. It involves a great deal of project fields, such as project of highway and bridge, the hydrological and hydroelectric engineering, architectural work, etc. So the stability of slope has been an important research content of the soil project circle of rock all time.In slope project, the traditional evaluating method is factor of safety method. The method treats various kinds of design condition, design index and parameter as fixed values. But such traditional method has neglected the uncertainty of the soil properties parameter, and does not conform with reality. In recent years, people have realized the uncertainty in the soil project question gradually. People have introduced probability analysis method into slope project, considered all sorts of uncertain factors existing actually in rational by way of probability, So it can reflect the real safety character of slope for objective.Monte-Carlo simulation method is an accurate technique for estimating failure probability and reliability index of the slope stability. In this paper, the Monte-Carlo method is applied to analyze the reliability of soil slope stability and to discuss the influence of correlation among the fundamental variables, the averages and variation coefficient of soil parameters on the reliability index based on engineering examples. Compiling the corresponding programs, and study the regularity among them. The conditions made is meaning of consulting very much in the probability index of slope stability analysis in the future.
