摘要
某水库作为北江引水工程的备用水源,由于其运行调度的变化,需要对该水库在应急取水和蓄水回补过程中坝体稳定状况进行分析。该文以理正岩土5.5与stab2009为计算软件,重点研究水位骤降与水位升高过程中该水库上、下游坡的稳定,同时对于处于不稳定状态的坝坡提出切实可行的加固方案。
As an alternate source of Beijiang water diversion project , due to the change on operation , the dam slope stability of res-ervoir need to be analyzed in the process of emergency water intaking and impoundment .In this paper , by using of LIZHENG 5.5 and STAB2009, the research is emphasized on slope stability of upstream and downstream of the reservoir in the process of rapid drawdown and raise of water level .At the same time , feasible reinforcement scheme is put forward for the dam slope in the unsteady state.
