摘要

影响工程岩体抗剪强度参数的因素很复杂，建立定量与定性相结合的多指标综合模型可有效地确定岩体抗剪强度。将多元非线性统计方法引入到岩体抗剪强度指标的研究中，选取了12个影响岩体抗剪强度的定性、定量指标，通过收集到的大量工程数据，分别建立凝聚力和内摩擦角非线性显式方程，决定系数分别为0.992 729，0.999 998。该方法可考虑定量、定性因素的影响，经现场实测数据验证，该模型具有较高的计算精度。运算过程简单，可方便工程现场使用，具有较高的工程实用价值。

Abstract

Factors affected the rock mass shear strength parameters are complex with uncertainties. A comprehensive model with multiple index is established combined with quantitative and qualitative indicators. It can effectively determine the shear strength of rock. The multivariate nonlinear statistical method is introduced to study the rock mass shear strength parameters. Twelve qualitative and quantitative indicators are selected

based on the large number of projects through the collection of data

nonlinear explicit equations of cohesion

and friction angle for rock mass shear strength are established; their determining coefficients are 0.992 729

0.999 998

respectively. This model not only considers quantitative factors

but also considers qualitative factors. It is verified by field data. Results show that the models have high accuracy. It is easy to solve the rock mass shear strength parameters with high practical value

and it has high practical value for projects.
