摘　　要：龙口水利枢纽坝基岩体主要由奥陶系中统马家沟组(O2m2)灰岩组成,其中发育有多层软弱夹层。作为其中之一的钙质充填夹层,强度虽不很低,但由于处于坝基下的持力层内,间距不大,发育密集,产状平缓,是坝基浅层抗滑稳定的主要控制因素,因此,在大坝抗滑稳定分析时,应进行分析和研究。The dam foundation rock of Longkou Water Control Project is mainly comprised of Ordovician system of Majia valley group (O-2m-2) doline, in which there are many layers of soft interbedded layers developed. As one of the cacareous filling interbedded layers, the strenth is not so low, but it is located in the supporting course under the dam foundation. The space is not big , it developed condensely and grow condition is gentle and it is the main controlling factor in shallow stability against sliding of dam foundation. Therefore, when the analysis of stability against sliding for dam is done, the analyze and research must be conducted.
