摘　　要：通过对高拱坝库盘实测变形进行分析,库盘整体呈坝前下沉、坝后相对基准点略有抬升的翘曲变形。研究了库盘变形的影响因素,结合小湾工程,建立包括库区、坝基和大坝的大范围数值模型,开展高拱坝库盘变形对大坝工作性态影响的初步研究工作。研究成果揭示了库盘变形的一般性规律,并提出了评价大坝工作性态时应考虑库盘变形影响的建议。Based on the monitoring data of high arch dam reservoir basin deformation, it is found that the reservoir basin shows a warping deformation with settlement in front of the dam and a little uplift behind the dam. Therefore, in order to study the deformation of high arch dam reservoir basin and its effect on darn operating behavior, the affecting factors are studied firstly, and then, the numerical model is built for Xiaowan Hydropower Station Project, in which, the reserwfir area, dam foundation and dam are included. The research results reveal the general law of reservoir basin deformation. It is also proposed that the deformation caused by reservoir basin should be taken into consideration when evaluating dam operating behavior.
