摘　　要：简要介绍了钻孔变形试验的基本原理和动静对比的方法,动静对比关系在小湾水电工程中的应用。通过动静对比关系将岩体弹性波测试的速度空间分布规律转化为变形模量分区,从而为岩体与坝基应力分析和稳定性评价提供定量依据。This paper introduces the basic principles of borehole deformation test,the static and dynamic comparison method and the application of static and dynamic comparison in Xiaowan hydropower project. Through establishing the relationships between the static and dynamic characteristics,the spatial distribution of rock elastic wave speed will be transformed into deformation modulus district. It provides the quantitative basis for evaluating the stability and analyzing the stress of the rock and dam foundation.
