摘　　要：黄河龙口水利枢纽坝基持力层存在多条平缓泥化夹层及糜棱岩状夹层，对坝基的深层抗滑稳定极为不利，必须采取工程措施对泥化夹层及摩棱岩进行处理，以满足深层抗滑稳定要求，本文分析比较了多种工程措施，推荐采用坝踵深齿槽方案加固坝基。There are several gently clay seams and mylonitic interlayers in holding strata to seriously adverse to stability of deep sliding of damfoundationThe engineering measures for clay seams and mylonitic interlays must be taken in order to meet with the requirement of stability of deep slidingThis article compares several engineering measures,and recommends use of deep cutoff trench at dam heel to consolidate dam foundation
