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。
The observation items of lower pool CFRD at Xikou Pumped storage Station are internal settlement and horizontal displace-ment,displacement of peripheral joint and slab joint,strain of face plate and pore water pressure at dam foundation Based on the obser-vation data till2000,the regularities of the observed variations are analyzed,the operation situation of the dam is evaluated.
