摘要
在拱坝设计中,如何选择合理的拱坝体形仍然是一个需要探讨的重要问题。二滩拱坝高240m,坝址河谷呈基本对称的“V”型,宽高比3.21。作用于坝上的总水压力约1000万t,坝体应力及作用于坝基的推力均较大,致使拱坝体形设计难度很大。本文结合二滩拱坝体形参数的确定过程,阐述该坝体形选择的合理性;并试图通过对拱坝结构受力特点的分析,探讨混凝土抛物线双曲拱坝体形参数的选取问题。
Ertan arch dam is located in the roughly Symmetric valley of V-type with 240m in height and widthheight ratio 3.21, the total water pressure on the dam is about 10 million tons and the dam stress and the thrust on dam foundation are tremendous, so there is big difficulty in arch dam type design. In the process of determining type parameters of Ertan arch dam the rationality of dam selection is described in this paper. The parameter selection problem of concrete parabolic double-curvature arch dam is tried to investigate through bearing capacity analysis of arch dam structure.
