水闸底板的应力分析,是水闸设计中的重要课题。边荷载对水闸底板的应力往往有举足轻重的影响,因为在边荷载作用下,底板应力可以达到与闸上荷载产生应力的同等数值。目前,在边荷载作用下底扳应力的计算中,趋向于考虑地基变形的时间效应,但这方面的一些设计规定在概念上是不明确的,在计算应力的定量方面任意性较大,有的计算方法需要进一步商讨。这些问题的解决,都要研究底板的徐变应力。
The stress analysis of the sluice bottom plate is an important issue in the design of sluice gates. The side load often has a significant effect on the stress of the sluice bottom plate, because under the side load, the stress of the bottom plate can reach the same value as the stress caused by the load on the sluice gate. At present, in the calculation of the bottom wrenching stress under side loads, the time effect of ground deformation tends to be considered. However, some design rules in this area are conceptually unclear, and the arbitrariness of the calculated stress is relatively arbitrary. The calculation method needs further discussion. To solve these problems, we must study the creep stress of the floor.
