摘要
根据三峡库区危岩破坏的主要荷载组合,运用极限平衡理论及岩体结构理论分别针对滑塌式、倾倒式和坠落式三类危岩建立了危岩锚固计算方法,并在三峡库区的危岩稳定性分析及治理工程中进行了应用。
Dangerous rock mass is one of the two typical geologic hazards in the Three Goress reservoir area, and it is caused by factors of geologic strata, geomorphologic characteristic, fissure water pressure and earthquake etc. On the basis of possible mode for dangerous rock mass to fracture, the authors divided the dangerous rock mass into three models. slide dangerous rock mass(SDR), topple dangerous rock mass(TDR) and fall dangerous rock blocks (FDR). In the course of controling dangerous rock mass, we must select the control technique such as drain, clearance, bearing, anchor and retain etc. To some extent, anchor is an important one in these techniques. However, there is not any reasonable method to make anchor calculation of dangerous rock mass. Based on the main load compose for dangerous rock mass to fracture, anchor calculating method is established by limit equilibrium theory and rock mass structure theory. The method has been gotten the extensive application in control in this region.
