矿山岩体边坡强度参数选取研究

摘要

In rock slope stability study,the slope rock mass strength parameters usually needed to be known. And experiment usually provides slope rock strength parameters. Therefore,how to convert Chengbianpo rock parameters stability analysis of rock mass needed parameters of rock slope stability analysis is very important,the results of the analysis on the slope stability has great influence. The domestic and international in common use in the intensity parameter transformation methods for comparative analysis was studied. Meanwhile,the modem BP neural network method was used in the slope rock mass strength parameters of the conversion. It was used in the practical slope stability study,and the application effect is remarkable.%在进行岩质边坡稳定性研究中,通常需要边坡岩体的强度参数,而室内试验提供的通常是边坡的岩石强度参数.因此,如何将岩石参数转换成边坡稳定性分析所需要的岩体参数,对岩质边坡稳定性分析至关重要,对边坡稳定性分析的结果影响极大.为此,对国内外边坡研究中常用的强度参数转换方法进行比较分析,并指出其适用范围.同时,将现代BP神经网络方法引入边坡岩体强度参数转换,并应用于具体边坡稳定性研究,应用效果较好.
