摘要
针对益阳灰坝坝体渗漏情况,从坝体填筑质量、排渗系统和副坝高浸润线等方面探讨了渗漏原因并分析了渗漏机理,采用一般极限平衡法(GLE)对坝体渗漏严重部位进行稳定性分析。计算表明,初期坝体稳定,终期坝在干滩50 m时是不稳定的。
The leakage is enlarging after the foundation of Yiyang ash dam and it threatens the operational safety. In order to solve the serious leakage in Yiyang ash dam,on the base of the field survey and experimentation, we probe into the leakage root from the dam quality,its drainage and the soakage line of slave dam,and analyze leakage theory. The generalized limit equilibrium method （GLE） is applied to analyze the stability of ash dam. Through comparison of the ＂stopping up＂ and ＂drainage＂, feasible measures including the design of drain with the radiated well are presented and the stability of ash dam is improved.
