摘　　要：中国贵州高生水电站大坝坝基开挖过程中,现场实际揭露的地质条件表明坝基岩体风化程度不高,大坝基础有优化调整的基础条件。通过采用刚体极限平衡法、材料力学法、有限元法进行坝体抗滑稳定和应力计算、分析和复核,同时通过三维整体有限元复核,其大坝应力、坝基应力、大坝建基面抗滑稳定及深层抗滑稳定均满足规范要求,工期及投资效益明显。During the excavation of the dam foundation of Gaosheng Hydropower Station in Guizhou Province,China,the geological conditions revealed in the field show that the weathering degree of the dam foundation rock mass is not high,and the dam foundation has the foundation conditions of optimization and adjustment.Through the rigid body limit equilibrium method,material mechanics method and finite element method to calculate,analyze and recheck the anti-sliding stability and stress of dam body,and through the three-dimensional overall finite element recheck,the dam stress,dam foundation stress,anti-sliding stability of dam foundation surface and deep anti sliding stability all meet the specification requirements,and the construction period and investment benefit are obvious.
