【摘要】 以缅甸高地震区某电站为例,针对坝基岩体存在不整合面(带)、缓倾角及中倾角、陡倾角裂隙问题,采用被动抗力法分析计算了该地区重力坝方案深层抗滑稳定性,并分析了各种荷载工况下的安全裕度,提出了裕度不足的基础处理措施。更多还原

【Abstract】 The rock mass of dam foundation exists unconformity face(band),low-angle,middle-angle and steep-angle dip crack.Taking a hydropower station in active seismic zone of Burma for an example,the passive resistance method is adopted to calculate deep stability against sliding of gravity dam.And then the safety margin is analyzed under the conditions of various loads.Finally,the measure of insufficient margin is put forward to deal with dam foundation.更多还原
