| 摘 要： | 对某300m级超高直心墙堆石坝及作为比较方案的弧形直心墙堆石坝进行了三维有限元应力变形计算.对2种坝型在蓄水期心墙的应力、变形进行了比较分析,结果表明:蓄水期,弧形心墙堆石坝比直心墙堆石坝的水平位移和沉降略小；弧形心墙坝的心墙拱效应较弱,其抗水力劈裂能力优于直心墙堆石坝；弧形心墙堆石坝坝肩处的应力水平小于直心墙堆石坝的... |

| Abstract: | The stress and deformation of a high rockfill dam with vertical core and with arc core is investigated by using three-dimensional finite element method.The stress and deformation of the two kinds of dams in the period of water storage is analyzed.The results show that the horizontal displacement and vertical displacement of the dam with arc core is slightly smaller than that of the rockfill dam with vertical core after the waterstorage.The arch effect of the dam with arc core is relatively weaker,and its ab... |
| Keywords: | rockfill dam arc core three-dimensional finite element stress and deformation |
