【摘要】 极端冰雪灾害条件下,冰胀力是影响边坡危岩体稳定的重要因素。首先介绍了基于弹性理论的结构面冰胀力解析算法。引入"等效线膨胀系数"概念,对结构面冰胀力进行了数值模拟分析,并对两种算法的成果进行了比较,发现两种方法计算出的冰胀力十分接近,验证了两种方法的正确性,为极端冰雪灾害条件下边坡危岩体稳定分析提供了理论依据。更多还原

【Abstract】 Ice expansion force is a key factor affecting the stability of dangerous rock mass in slope under the condition of extreme ice and snow hazard.We firstly introduce the analytical method of ice expansion force for structural plane of dangerous rock mass based on elasticity theory.By introducing the concept of "equivalent line expansion coefficient",we conduct numerical simulation of ice expansion force of structural plane and compare the simulation results of the two methods.We find that the values of ice expansion force calculated by two methods are close,which verified the correctness of the two methods.更多还原
