本文叙述了用石膏块模拟节理岩体的三轴压力试验研究成果,并在此基础上提出节理岩体应用断裂力学强度模型和有限元方法。最后,本文应用上述断裂力学模型对二滩拱坝坝肩岩体稳定进行了分析。
This paper describes the results of triaxial stress test of jointed rock masses simulated by gypsum blocks, and on this basis, the fracture mechanics strength model and finite element method for jointed rock masses are proposed. Finally, this paper applies the above-mentioned fracture mechanics model to analyze the rock stability of Ertan arch dam abutment.
