摘　　要：高坝大库库盘变形通常都比较显著,部分对大坝的运行性态有较为明显的影响。但目前国内外对库盘影响作用下的大坝运行性态分析评价较少,现行的规程规范涉及此方面的规定也不多。以龙羊峡水电站大坝为例,利用库区和大坝的实测资料,对其进行计算分析,研究在库盘变形影响作用下大坝的运行性态,并对其相关的变形和力学参数进行反演计算,为下一步大坝建立相应的监控指标和监测预警体系奠定了基础。Deformation of the high dam reservoir basin is usually significant,and some of them have a significant impact on the operational behavior of dams.However,at present,there are few analysis and evaluations on the performance of dams under the influence of reservoir basin at home and abroad,and there are few regulations concerning this aspect in current specifications.Taking the dam of Longyangxia Hydropower Station as an example,the measured data of the reservoir area and the dam are used to calculate and analyze the dam's operational behavior under the influence of reservoir basin deformation,and inversion calculation is carried out for the related deformation and mechanical parameters.The feedback analysis has laid the foundation for the establishment of corresponding monitoring indicators and monitoring alarming systems for the dam.
