RELIABILITY ANALYSIS OF ROCK SLOPE STABILITY IN GUANGZHOU SCIENCE CITY

The slope stability is the most important problem in the slope engineering.How to study the problem is one of the major subjects in geotechnical engineering.The widely used Monte Carlo method is adopted in this paper to analyze and evaluate the reliability of slope stability,which is popular in the geotechnical engineering.Before the simulation is performed,the limit state function is established on the basis of traditional limiting equilibrium theory.During the calculationt,he probability theory,mathematical statistics and some other necessary mathematical algorithms are used in the calculation program.The pseudo-random variable will be created by the computer program,and then the reliability index and failure probability of slope can be figured out by the Monte Carlo simulation technique.All the calculation and analysis processes are performed automatically by the computer program designed by Microsoft VC++ program language.Analytical results will be output in the form of charts and tables.The practical application in the reliability analysis of rock slope stability indicates that more effective information about the slope stability can be gained by the Monte Carlo method.The conclusion can be drawn that reliability analysis is a new trend to the slope engineering.Compared with the traditional limit equilibrium method,the reliability analysis can directly reflect the failure probability and degree of reliability of slope,which can provide more reliable parameters for the design of slope engineering and direct the construction.In a wordt,he reliable analysis method of slope stability is a new and effective method with extensive prospect and will be widely used in the geotechnical engineering.
