摘要
本文扼要介绍了单孔声波、全孔壁数字成像测试原理及小湾电站坝基岩体长观测试结果。通过对坝基岩体的声波、全孔壁数字成像测试资料的统计分析，在深度方向上对小湾水电站坝基岩体宏观分为三带：松弛带、过渡带和正常带，并总结出各岩体带的声波衰减率曲线及裂隙发育特征。
The principle of wave velocity and borehole imaging measurement and results in Xiaowan HydropowerStationps Foundation Rock are presented o Foundation Rock Mass divide into three zones by Geophysical Prospecting statistical tables and graphs o To make a summary about the feature of three zones in end.
