【摘要】 分析目前确定岩体参数方法中存在的一些困难,通过把岩体的完整性系数同岩体微裂纹密度参数结合起来,运用细观损伤理论,得到确定岩体参数的计算方法,并分别运用Taylor方法和广义自洽法结合工程实例和部分统计资料进行计算对比分析,根据计算结果,结合BQ法针对完整性系数小于0.5的情况进行修正。研究结果表明,该方法合理可行,避免传统方法的经验差异或人为因素的影响。更多还原

【Abstract】 Some difficulties are found on the current methods to determine rock parameters. By combination of intactness index of rock mass with microcrack density,the analytical method of rock mass parameters is obtain on the micromechanical damage theory. The Taylor method and the generalized self-consistent method are used combining with practical examples and some statistics;and the method is modified according to calculation results combining with BQ method when the intactness index of rock mass is less than 0.5. The results show that it is reasonable and useful in avoiding artificial influence and experience differences of traditional methods.更多还原
