摘要
超深岩石基坑的破坏机理与土质基坑有本质的区别。通过对实例进行数值模拟分析,揭示了超深岩石基坑的破坏模式与破坏机理随基坑深度的变化规律,并且分析了预应力锚杆加固超深岩石基坑的作用机理和加固效果。
There is an essential difference in failure mechanism between extra-deep excavation in rock and soil one.Based on the numerical simulation of the real extra-deep excavation,the relations of the fracture types and the fracture mechanism with depth of the excavation are studied.The working principles and the reinforcement effect by means of pre-tensioned bolts are analyzed.
