摘要
东风水电站枢纽由双曲抛物线薄拱坝、泄洪系统、地下厂房系统和防渗帷幕系统组成,并建立了原型观测系统。水库蓄水初期(库水位950m以下)对大坝变位、基础变形、渗流渗压、扬压力进行了观测,其成果和大坝设计计算值基本上是吻合的,变形性态和设计预测的性态基本上是一致的,说明大坝的运行状态正常。对个别变形较大和渗压较大的部位,需进一步加强监测。
ongfeng Hydropower Station consists of a double-curvature arch dam, flood discharge system, underground powerplant, and leakproof grout curtain system. A prototype observation system was also set up. In the early impounding stage, dam dislocation, foundation deformation, seepage pressure, and hydraulic uplift pressure were observed. The data basically bellies with the calculating values of dam design. The deformation properties also tallies with the properties projected in design. This shows that the dam operates normally under water elevation of less than 950m. However, some points with larger deformation or larger seepoge pressure must further be monitored.
