Abstract:

Yulong Kashi water conservancy project is located in the high mountain and gorge area with steep bank slope. The basic intensity of site seismic is Ⅷ, and the seismic fortification intensity of dam is Ⅸ. It is a 230 m high earth-rock dam in the mountainous-valley reach where is cold and has strong earthquake. According to the construction conditions of earth-rock dams in the project area, the present situation of high earth- rock dams in strong earthquake areas at home and abroad is studied in detail. Three types of earth-rock dams are determined for comparison and selection, and the feasibility analysis is carried out one by one. Finally, the concrete face rockfill dam is selected as the recommended dam type. At the same time, the difficulties in dam design and the specific direction of scientific and experimental research are pointed out.

摘要: 玉龙喀什水利枢纽位于高山峡谷区,岸坡陡峻,场地地震基本烈度Ⅷ度,大坝地震设防烈度Ⅸ度,为强震、寒冷峡谷山区河段上的230 m级高土石坝。笔者根据工程区土石坝建设条件,详细统计了国内外强震区高土石坝现状,确定了可参与坝型比选的三种土石坝坝型,并逐一进行可行性分析,最终确定混凝土面板堆石坝为推荐坝型。同时,也指出了大坝设计难点和目前开展科研试验研究的具体方向。
