2.力学性质图4表明设计方法的应用与力学性质密切结合,特别是:滑弧和复杂滑动面方法,剪切强度;有限元的静态分析,强度和形变特征,包括应力、应变间的关系。有限元法的动态分析,动态剪切强度,动态形变率和衰减系数,必要时,对动态应变强度提出再定量。这些力学性质能够由现场试验获得的结果来较好地确定。(1)关于强度或变形特性,许多作者已经提出过理论的或实际的经验公式。以岩 2. Mechanical Properties Figure 4 shows that the application of the design method is closely related to the mechanical properties, in particular: the method of sliding arc and complex sliding surfaces, the shear strength; the static analysis of the finite element, the strength and deformation characteristics, including the relationship between stress and strain . Dynamic analysis of finite element method, dynamic shear strength, dynamic deformation rate and attenuation coefficient, if necessary, the dynamic strain strength proposed quantitative. These mechanical properties can be better determined from the results obtained in field tests. (1) Many authors have proposed theoretical or practical empirical formulas regarding strength or deformation properties. Rock
