THE APPLICATION OF GENETIC ALGORITHM IN NON-LINEAR INVERSION OF rock mechanics parameters

Journal of Coal Science & Engineering(China) 1998年第2期4卷 13-16页

作者：赵晓东

The non-linear inversion of rock mechanics parameters based on genetic algorithm is presented. The principIe and step of genetic algorithm is also given. A brief discussion of this method and an application example is presented at the end of this paper. From the satisfied result, quick, convenient and practical new approach is developed to solve this kind of problems.

Based on the classical static theory and static numerical simulation,the static method could not accurately reflect the stability of goaf where the rocks on the pillar and roof are influenced by Theological and blasting disturbance for a long *** to the test from the site,an experimental study was made in Theological and dynamic *** that,on the basis of variable rock mechanics parameters from the experimental data,numerical simulation was used to analyze the vertical stress distribution of goaf,vertical displacement and plastic area of roof in the "deterioration" caused by Theological and blasting,which shows that the mechanics properties of the rock were greatly influenced by Theological,and dynamic *** results of the experimental study and numerical simulation show that the mechanics properties of rock are greatly influenced by Theological and dynamic *** a result,the stability of goaf is greatly ***,by comparing golf monitoring results with the analysis of theoretical calculation,it was found that the results were approximately the same,which testifies the reliability of the *** method provides a new way of studying the stability of goaf as well as laying a basic foundation for future safety management.

Since the Wenchuan earthquake happened,the slope stability had been paid much more *** safety factor is an important parameter that can be used to evaluate the stability of slope. The pseudo-static method that based on limit equilibrium and the method of numerical simulation can calculate the safety factor accurately,but the velocity that gets the result is *** we can establish the relationship between safety factor and some other parameters,then we can calculate the safety factor by using the relationship more *** paper establishes much relationship,such as the relationship between the rock mechanics parameters and the average danymic safety factor,the relationship between the rock mechanics parameters and the ratio of average danymic safety factor to static safety factor,the relationship between the rock mechanics parameters and the average earthquake acceleration coefficient,the relationship between the average earthquake acceleration coefficient and the ratio of average danymic safety factor to static safety factor,and the relationship between the earthquake acceleration coefficient and the ratio of danymic safety factor to static safety factor on the condition of different rock mass.
