摘　　要：为研究库水位下降速率对链子崖T8～T12缝段危岩体产生的影响,并综合地震等因素评价缝段危岩体治理后的稳定性,采用改进的Sarma法分析了三种工况下库水位下降对治理后链子崖T8～T12缝段危岩体稳定性的影响。结果表明,在三种工况下治理后的链子崖T8～T12缝段危岩体处于稳定状态,该方法与实际情况相吻合。In order to study the influence of drawdown rate of reservoir water level on T8～T12 fracture sections of Lianzi Cliff and take earthquake and other factors into consideration, this paper evaluates the stability of the critical rock mass after treatment. Improved Sarma method is adopted to analyze the influence of the drawdown of reservoir water level on T8～T12 fracture sections at Lianzi Cliff in three different working conditions. The results show that the critical rock mass, T8～T12 fracture sections at Lianzi Cliff , is stable after treatment in three different working conditions; the im- proved Sarma method matehs the fact.
