摘　　要：针对目前重力坝安全监测预警系统关于抗滑稳定预警存在的不足,在混凝土重力坝设计规范(DL5108-1999)的基础上,以分项系数极限状态设计表达式得到了坝基抗滑稳定预警指标1.0;以双滑面深层抗滑稳定计算式推导出简化的分项系数多滑面计算式。将研究成果运用到监测预警系统中,编制了抗滑稳定预警分析软件。工程实例证明,在电站蓄水期和运行期,预警分析软件能够全程实时采集监测数据,对建基面和不同深层滑动面的安全状态实时分析,超过预警指标及时预警。For the deficiencies of the gravity dam safety monitoring and early warning system on the sliding stability monitoring,based on analyzing the Gravity Dam Design Code（DL5108-1999）,the early warning index and simplified multi-slip surface calculation method are put forward.Based on the theory of the anti-sliding stability calculation,the early warning analysis software of anti-sliding stability is developed.By applying the analytic software for the projects,the analysis software can analyze the security status of dam foundation by collecting monitor data and make warning in time.
