摘要
通过对河口村水库面板堆石坝沉降时效特性分析,探讨了坝基、坝体、大坝整体沉降变形特性,指出三者的沉降变形与坝基地质条件、填筑高程及时间密切相关,随着堆石坝坝高逐渐增加,最大沉降量约占坝高的0.72%,整体沉降变形量符合一般土石坝沉降变形规律。
According to the time effect analysis of settlement at concrete faced rock-filled dam at Hekou village reservoir,the paper explores the deformation features of general settlements at dam base,dam and great dams,and points out the close relationship among the settlement deforma-tion,the geological conditions of dam base,filling elevation and time effect,and indicates it gradually increases along with the added dam height of the rock-filled dams and the maximum settlement volume takes up about 0. 72% of the dam height,so the general settlement and deformation volume adheres to the common settlement and deformation law of rock dams.
