Abstract: The observation items of lower pool CFRD at Xikou Pumped storage Station are internal settlement and horizontal displacement, displacement of peripheral joint and slab joint, strain of face plate and pore water pressure at dam foundation Based on the observation data till 2000, the regularities of the observed variations are analyzed, the operation situation of the dam is evaluated.?

摘要: 溪口蓄能电站下库面板堆石坝最大坝高44.5m,施工期间布置的原型观测项目有坝体内部沉降和水平位移、周边缝和板间缝位移、面板应变以及坝基孔隙水压力。根据观测仪器自埋设至2000年的观测资料,文中分析了各项观测物理量的变化规律和变化趋势,综合评价了大坝的工作性态。
