摘要
针对土石坝安全鉴定对水库安全稳定的重要性问题,基于对大坝安全鉴定的要求,采用瑞典圆弧法、毕肖普法、工程师团法、罗厄法4种方法验算了8种工况下飞来峡水库主土坝坝坡的稳定性,并结合碾压式土石坝设计规范进行了分析对比。结果表明,各种水位下抗滑稳定安全系数均满足规范要求,为大坝除险加固设计提供了依据,对确保大坝安全运行具有指导意义。
Appraisal of earth dam safety is essential for safety and stability of the reservoir.According to the requirements of appraisal of dam safety,the stability analysis of dam slope of Feilaixia Reservoir has been carried out by using Sweden circular-arc method,Bishop method,Engineer Corps method and Lowe method under eight kinds of working conditions.Combined with design specification for rolled earth-rock fill dam,the calculation results are analyzed.The results show that the safety factors of anti-slide under all working conditions meet the requirements of the design specification.Thus,it provides basis for the reinforcement design of the dam,which also has directive significance for the safe operation of the dam in the future.
