摘　　要：万安溪面板堆石坝最大坝高 93 8m ,坝顶长 2 10m ,1990年 12月开工 ,1994年 8月开始蓄水。在施工期及运行初期布置了各种类型的观测设备 ,其中包括坝体内部和外部的位移观测 ,面板周边缝位移和板间缝开合度观测 ,面板应力和应变观测 ,大坝渗流量观测 ,以及面板上部裂缝监测。通过对 1999年观测资料的分析和评价 ,表明坝体变形总体正常 ,面板大部区域是压应变 。The Wan'anxi concrete face rockfill dam started to be built in December 1990 and impounded water in August 1994, with the maximum dam height of 93.8 m and the crest length of 210 m. During the construction period and the early operation, various observation devices have been arranged, including displacement observation inside and outside the dam body, the observation on the displacement of peripheral joint of face slab and the opening of joints among slabs, the slab stress and strain observation, and the crack observation in the top of face slab. The analysis and assessment on the observation data from 1999 up to now show that the deformation of the dam body is normal generally and the compressive strain occurs in the most area of face slab. The dam is stable with low seepage.
