摘　　要：利用8～21节点块体单元离散了小浪底1号进水塔,对工作门在挡水荷载作用下弧门段的应力进行了分析,计算了10个截面的内力值和闸室侧墙的应力状态.计算结果表明,细化计算所得弯矩在许多处有不同程度增加,而轴力和剪力则有相当程度减小.在侧墙内侧存在一个较大的拉应力区,其最大值为2 08MPa,建议设计单位采取其它的工程措施来解决侧墙大区域的双向受拉应力问题.In this paper, 8～21 node solid elements are used to divide the Xiaolangdi No.1 intake tower. Under water loading, in consideration of main gate shutting scheme, the stress analysis of radial gate section is presented. The internal force of 10 sections and the stress state of the sluice chamber side wall are calculated. The result shows that bending moment increases at different degree in particular division calculation, normal force and shear force both decrease at rather degree. There is a larger tensile stress zone with the maximum value of 2.08MPa. The design agency should consider other engineering measures for controlling double tensile stress of the side wall's larger zone.
