摘要
利用小湾水电站高拱坝库盘变形实测资料,结合数值模拟技术,对小湾高拱坝库盘变形的规律、量级以及对拱坝的作用效应等进行了深入的研究,监测成果显示高拱坝库盘变形及对大坝变形性态具有影响,巨大的水荷载作用致使库盘产生坝前沉降大于坝后沉降的"翘曲"变形,使得拱坝产生向上游倾斜变形现象。
Based on the measured reservoir basin deformation data of Xiaowan Hydropower Station, the deformation law and magnitude of reservoir basin deformation and the action effects on Xiaowan high arch dam are analyzed by using numerical simulation method. The results show the reservoir basin deformation has an impact on dam deformation behavior, the huge water load leads to the warping deformation of reservoir basin with the settlement before the dam greater than the settlement behind the dam and leads to the arch dam being tilted towards the upstream direction.
