【摘要】 考虑复杂地基及塔内外水体的影响,采用三维有限元法分析了两河口水电站进水塔的静动力强度与刚度,并校核了地震工况下进水塔的整体抗滑、抗倾覆与抗浮性能。同时针对该进水塔的尺寸特点,修正了规范给出的塔外地震动水附加质量计算公式。结果表明,两河口水电站进水塔的结构设计能满足相关规范要求。更多还原

【Abstract】 Taken complex foundation and water surrounding the structure into account,static and dynamic stiffness and strength analysis for intake tower of Lianghekou Hydropower Station are performed by using three-dimensional FEM.And the whole sliding,overturning and floating stability are checked under the earthquake conditions.According to the size of intake tower,the calculation formula of additional water mass outside the tower given by the specification is modified.The results show that the structural design of intake tower meets the requirements of correlated specification.更多还原
