针对四川省华蓥市某石灰岩矿区内存在的4处危岩，介绍了危岩体的基本特征，分析研究了其形成机制。在此基础上，选取天然状态、暴雨状态及地震力作用下3种工况，建立计算模型，对危岩体的稳定性进行了计算。结果显示，4处危岩体天然状态下均处于稳定状态；在暴雨状态下，有2处危岩体处于欠稳定状态，其余2处危岩体处于基本稳定状态；而在地震的影响下，有1处危岩体处于不稳定状态，其余3处危岩体处于欠稳定状态；危岩体存在发生崩塌破坏的可能。

According to the 4 dangerous rock mass exists a limestone mine area of Sichuan Province in Huaying City is discussed. Introduces the basic characteristics of the dangerous rock mass, analysis of its formation mechanism. On this basis, selected three kinds of natural state, rainstorm and earthquake force condition, and the establishment of calculation model, on the stability of dangerous rock mass is calculated. The calculation results show, 4 dangerous rock mass under natural condition is stable. In the rainstorm condition, there are 2 dangerous rock mass in less stable state, the remaining 2 of dangerous rock mass is in stable state. And the impact of the earthquake had 1 dangerous rock mass is in an unstable state, the remaining 3 dangerous crag in the steady state. There are likely to collapse.
