【摘要】 裂隙岩体结构面力学参数的取值是复杂而重要的．本文在深入分析其复杂性和各取值方法优缺点的基础上，结合工程实践阐述了最危险控稳结构面的确定以及采用工程地质类比法和相对位移反分析法合理确定结构面力学参数的理论和方法．研究结果表明，扎实的工程地质分析是合理确定结构面力学参数的基础，干扰能量法、模糊度量和相对位移反分析法在小浪底水利枢纽工程和江阴大桥工程中的应用取得满意的效果．更多还原

【Abstract】 The selection of the mechanical parameters of the structural surface of joint rock masses is complicated but important. On the basis of deep analysis of the complexity and merits and demerits of each selection method and in consideration of a practical project, the determination of the most dangerous, controlling structural surface is introduced and the theory and method of selecting the mechanical parameters of the structural surface by the quantitative geology analogy and the relative displacement back analysis are given. The conclusion is that solid geologieal analysis is the most important basis in selecting the mechanical parameters of the structural surface. The interference energy method, the fuzzy theory and the relative displacement back analysis have been sucessfully used to the Xiao Lang Di Hydroproject and the Jiang Yin Bridge project.更多还原
