摘　　要：红层地区软弱夹层较为发育,对水利水电工程的建设具有重大影响。根据黄石盘水库坝址区NJ2软弱夹层发育情况,通过对构造作用、岩体卸荷、岩性差异、地下水等地质因素和周期效应的分析,明确NJ2软弱夹层的成因。研究成果为黄石盘水库大坝的抗滑稳定提供决策依据,并为红层地区软弱夹层的成因提供参考。The weak interlayer is more developed in the red layer area,which has great influence on the construction of water conservancy and hydropower projects.According to the development of NJ2 weak interlayer in the dam site of Huangshipan Reservoir,the cause of NJ2 weak interlayer is defined through the analysis of geological factors such as tectonic action,rock mass unloading,lithology difference,groundwater and periodic effects.The research results provide the decision basis for the anti-sliding stability of Huangshipan Reservoir dam,and provide a reference for the causes of weak interlayers in the red bed area.
