本文初步探讨了允许底部滑动的拱坝设计方法,对拱坝设计有所改进,尚待工程实践。本文介绍一种允许底部滑动的拱坝设计方法。在较宽阔的河谷中,采用这种结构措施可以大大改善拱梁荷载分配,消除悬臂梁上游面的拉应力,充分发挥下层拱圈的承载能力,使得坝体各部位材料受力较为均匀,从而节约工 In this paper, the design method of arch dam that allows sliding at the bottom is preliminary discussed, and the design of arch dam has been improved. This article describes an arch dam design method that allows for bottom sliding. In the wider valleys, adopting this kind of structural measures can greatly improve the load distribution of the arch beam, eliminate the tensile stress of the upstream cantilever surface, give full play to the bearing capacity of the lower arch ring, and make the material stress of the various parts of the dam more uniform.
