摘　　要：横断山区作为我国最大的水能基地,随着中国水电开发事业的发展和应对全球气侯变化、节能减排的需要,有必要加大该地区丰富的水电资源的开发,但横断山区的河流大部份处于深山峡谷中,受高边坡和恶劣气候的影响,河床两岸表层岩石风化剥蚀严重,表现出大面积的碎裂结构岩体分布,给水电站建设带来坝肩开挖工程量大或边坡失稳的影响。由于碎裂结构岩体与下覆基岩物性差异较小,探测难度较大。本文针对碎裂结构岩体的勘探问题,采用综合地震勘探方法进行分析研究,取得了良好的应用效果。Hengduan Mountain Region is the largest hydropower base of our country. With the development of China＇s bydropower and response to the global climate change, the need of energy conservation and emission reduction, it is necessary to intensify the development of this region which is rich in hydropower resources. Most of rivers in Hengduan Mountain Region are located in valley, influenced by high slope and bad weather. Surface rock of two riverbeds is seriously weathering in erosion, so there is a large area of cataclastic rock structure which causes huge excavation work or slope instability problems for hydropower station construction. Since the difference between the property of the cataclastic rock and that of under rock is small, it is hard to detect it. This paper uses comprehensive seismic method to analyze and obtain good application effects.
