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2.08 MPa,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.

Abstract:

The No. 8 water intake tower of Xiaolangdi was discretized by using the 21~1 node block unit, and the stress of the arc door section of the working door under the water retaining load was analyzed, and the internal force value of 10 sections and the stress state of the side wall of the lock chamber were calculated. The calculation results show that the bending moment obtained by the detailed calculation increases to different degrees in many places, while the axial force and shear force decrease to a considerable extent. There is a large tensile stress area on the inside of the side wall, the maximum value is 2.08 MPa, and it is recommended that the design unit take other engineering measures to solve the problem of bidirectional tensile stress in the large area of the side wall.
