本文在汇集了28个国家的458个拱坝资料的基础上,对目前各国拱坝建设发展中的一般趋势和特点作了初步的探讨性的分析,包括修建拱坝的地形地质条件、基础处理和拱坝设计中的规范,以及坝高、坝型等。并附有对各国拱坝河谷断面宽高比(L/H)和坝体断面厚高比(B/H)关系曲线及各国拱坝河谷断面系数(K)和坝体断面厚高比(B/H)关系曲线,以供设计人员选定初始断面时的参考。 Based on the data of 458 arch dams in 28 countries, this paper makes a tentative and tentative analysis of the general trend and characteristics of arch dams in various countries at present, including the topographic and geological conditions of arch dams, basic treatment And arch dam design specifications, as well as dam height, dam type and so on. The curves of aspect ratio (L / H) and dam height-to-thickness ratio (B / H) of arch dam valley in different countries and the cross section coefficient (K) / H) relationship curve, for the designer to select the initial section of the reference.
