摘　　要：八泉峡水库坝基开挖过程中,出现因应力变形作用造成基坑底鼓、岩体软化及软弱夹层等不良地质情况,通过合理的勘察方法进行分析、研究,评价上述地质情况对坝基稳定性的影响,提出合理工程处理措施。During the process to excavate dam base of Baquanxia Resevoir,some harmful geologic phenomenon appeared including bottom bulging of foundation pit due to stress deformation action of rock,rock body softening and weak rock interlayer.In this paper,through reasonable exploration method,the influence of above-mentioned geologic phenomenon on stability of dam base is analyzed,studied and evaluated,and reasonable project treatment measures are put forward.
