摘要
岩土参数是影响边坡稳定性分析结果准确性和可靠性的重要影响因素之一。论文介绍了目前参数确定的主要方法:试验法、经验类比法、公式估算法、岩体质量分类法、反演法,分析了影响参数确定的主要因素,提出了一个优化确定岩土参数数值的综合方法。在伊敏露天矿东南帮边坡稳定性分析中,应用该方法确定东南帮边坡地层中泥岩的抗剪强度参数,得到较合理的参数值,获得了较准确可靠的稳定性分析结果。
The rock and soil parameters are one of the important factors influenced to the accuracy and reliability of slope stability analysis results.This paper introduces main methods to determination of geotechnical parameters presently,which are test method,empirical method,the empirical formula method,rock mass quality classification and determination of inversion method,analyses the main factors affecting determination of geotechnical parameters and puts forward a comprehensive method about parameter optimization.In the slope stability analysis of Yimin open-pit coal mine,by this comprehensive method,more reasonable parameter values were got,more accurate and reliable analysis results were obtained in determining the shear strength parameters of mudstone measured in the southeast slope.
