摘　　要：鉴于李家峡库区复杂的地质情况及较长的蓄水历时,结合水库初次蓄水以来的拱坝垂直位移观测资料对坝体及坝肩岩体的垂直位移及其物理成因进行了分析,认为李家峡拱坝坝体及坝肩岩体的垂直位移基本正常,整个坝体变形安全性态良好.As the complicated geology and longer storage duration of Lijiaxia reservoir, based on the vertical displacement data which was obtained after the preliminary stage of storage of the darn, the displacement and its physical cause are analysis qualitatively and quantitatively. The results indicate that the dam and the base rock vertical displacement are normal and its displacement safety characters are all right.
