观音岩水库工程碾压混凝土拱坝建基面（河床段）抬高论证

摘要

According to geological conditions which are excavated in the Guanyinyan reservoir arch dam foundation ( ri-verbed),the paper rechecks rock weathering line ,rock quality,mechanics parameters by the exploration means of single , across hole ultrasonic and electromagnetic wave CT test ,rock test etc .,and then demonstrates the geological conditions of dam foundation elevation .%根据观音岩水库拱坝建基面（河床段）开挖揭露地质条件，运用单、跨孔超声波以及电磁波CT测试、岩石试验等勘察手段，进一步对岩体风化线、岩体质量、力学参数进行复核，从而论证建基面抬高的地质条件。
