摘要
处于碳酸盐岩分布区的汾河二库，岩溶发育呈互不连通的河岸岩溶孔洞、河谷深部网络状岩溶管道和河床顺层溶蚀裂面三种类型．针对坝区白云岩结构和岩体结构面岩溶发育的规律，论述了坝区岩溶的特征和岩溶工程地质问题，并提出了齿槽处理、固结灌浆及设置防渗帷幕与排水等工程措施．
Fenhe ⅡReservoir is located in karst region. The karst features are 3 type of inconsecutivekarst hole, network karst passage in river valley and river bedding karst fracture plane. According to the struc-ture of dolomite rock and the regular of karst, the karst features in dam area are discussed. Some enginerringtreatment measures such as cutoff trench, consolidation grouting, seepage control curtain and drainage have beabopted.
