【摘要】 利用ANSYS软件对景洪水电站右冲沙底孔坝段在爆破开挖条件下进行动、静分析,并将时程法引入到承载能力极限状态设计分析方法中,进行稳定验算。结果表明爆破地震效应对右冲沙底孔坝段的抗滑稳定有较大的影响,但不会危及坝段的整体稳定,并根据计算结果确定各个爆破开挖阶段控制点的安全控制振速。更多还原

【Abstract】 The ANSYS software was adopted to analyze dynamic and static stress of right alluvial soil dam section of Jinghong water power station under blasting vibration condition,and the temporal analysis method was introduced into the ultimate state of bearing capacity analyses.The result shows the blasting seismic vibration has a remarkable effect on but does not endanger the stabilization of dam section.Finally,the calculated results were used to determine safety particle vibration velocity of every excavation blastings.更多还原
