中文摘要：
大坝安全监控指标是监控大坝安全的重要内容，然而现有的监控指标拟定方法由于与大坝安全联系不密切，从而拟定的是大坝异常的监控指标．根据大坝转异的基本特征，从结构分析方法出发，结合运动稳定性理论求解大坝的极限状态，并根据大坝实际工作的不同安全状态，拟定相应的安全监控指标．最后，把该方法应用到某拱坝中，为该工程的安全监控提供科学依据．
英文摘要：
Dam safety monitoring indices are an important aspect in monitoring dam safety. But the existing theory and methods only establish the monitoring indices of abnormity of dams because of not closely con- necting with the dam safety. This paper firstly analyzes the basic characteristics of dam abnormity, and then gets the dam limit state based on the structural analysis method and the motion stability theory. Sec- ondly, the corresponding dam safety monitoring indices are established based on the actual safety state of dam. Finally, the method is applied to the Xiaowan arch dam so as to provide a scientific foundation for its safety.
