摘　　要：本文系统研究了小浪底工程的岩体的强度特征,采用了室内试验,野外结构面统计,工程地质类比法、模型试验法和Hoek Brown的经验法,估算了工程岩体的力学指标,指出了上述各种方法中所存在的不足,认为在工程实践中,应尽可能使用多种估计方法,交叉校核所得参数,以提高参数的可靠性,保证工程的安全,节约投资。The shear strength of rock mass of Xiaolangdi Dam is investigated herein. In order to determine the parameters, intact rock compression test in the laboratory, surveying and sampling of geometric characteristics of joints are conducted. Engineering geological comparison method, analytical method and Hoek-Brown criterion based on the RMR classification are used to estimate the shear strength. These methods are reviewed as well. It concluded that various methods and engineering judgment are suggested in order...
