摘要
为了对某电厂灰渣库运行情况进行安全性评价,通过综合分析灰渣坝库区地形地貌、地层岩性、水文地质条件及灰渣坝现状,采用数值模拟方法对储灰场边坡的稳定性进行了分析,结果表明储灰场边坡处于不稳定状态。为保证灰渣库的安全,消除危险源,针对具体情况,提出了初期坝加固、为扩容新建一加筋体灰渣坝、防渗排水、卸渣的综合处理方案。
In order to evaluate the security of operation condition in an ash storehouse of certain power plant,through the comprehensive analysis of the landform and topography,stratum lithology,hydrogeologic conditions and the status of an ash dam of reservoir,the stability of the slope in the ash field is analyzed with numerical simulation,the results show that the slope of ash is in an unstable state.In order to ensure the safety of the ash storehouse and eliminate dangers,aimed at the specific situation,the comprehensive treatment measures are put forward including to reinforce the initial dam,build a new reinforced ash dam,anti-seepage and drainage,and remove the ash from the top.
