摘　　要：通过对盖孜水电站蜗壳及外围混凝土结构联合承载力进行有限元计算分析,假定在3.2 MPa的充水保压值下,对蜗壳的打压顺序进行分析,通过计算最终确定先打压后浇筑的施工顺序。Through the finite element analysis and calculation of the combined bearing capacity of spiral case and surrounding concrete structure of Gaiz Hydropower Station,the pressure sequence of spiral case is analyzed under the assumption of 3.2MPa water filling pressure holding value.Through calculation and analysis,the construction sequence of first pressing and then pouring is finally determined.

关 键 词：金属蜗壳 充水保压 打压顺序
