摘　　要：毛家河水电站枢纽区由于地质条件复杂,随着地质勘探工作的不断深入,揭露出坝基摆佐组(C1b2)风化带内原生泥页岩夹层次生泥化普遍,新鲜基岩为炭质灰岩与炭质泥页岩互层,因此大坝深层抗滑稳定问题凸显。要较好地解决该水电站大坝的深层抗滑稳定问题,需采取相应工程措施或调整大坝体形,使其在满足抗滑稳定的前提下,施工最方便、增加投资最少、影响工期最短。Geological conditions of Maojiahe hydropower station pivot area are very complex, in pace with geological survey work going deep, engineer had discovered that there usually are gault clay among some original argillaceous shale strata of weathering belt in dam foundation, and fresh foundation rock strata are carbonaceous limestone alternating with carbonaceous shale. The stability against sliding in deep stratum of the dam became a key problem. In order to solve this problem some engineering measures need be adopted, or body shape of the dam need be modified. The body shape modifying of the dam not only met stable conditions against sliding but also made construction convenient, invest less and construction period short.
