| 摘 要： | 坝前抛石压重加固病险水库已是一种经济,有效的加固措施,但规范和设计手册均无规定压重长度和高度的尺寸取值,其对大坝稳定影响效果不明确。针对这一问题,结合杨庄水库工程采用简化毕肖普法探讨了不同压重长度及高度,在正常运行稳定渗流的情况下对土石坝抗滑稳定的影响,得出压重长度应为0.45～0.55倍坝高,高度应至少在0.19倍坝高以上,越高则安全系数越大,但不宜超过0.3倍坝高。

| Abstract: | It is an effective and economical measure to reinforce sick and dangerous reserviors by means of ripped-rock weights.However,The toe weight length and height values are not difined in the standard and design handbooks,and its effect on the dam stability is not so obvious.To solve this problem,we discuss the size of the riprap toe weight against to the anti-slide safety coefficient on the basis of theYangzhuang Reservoir Project through simplified Bishop method.It shows that the length of the toe weight shou... |
