一、前言目前国内外常用的河弯水位超高计算公式不少,多数源于标准河弯模型试验或纯理论推导,与天然河道和山区河流的特性不尽相符,有必要对山区河流的河弯水位超高计算公式进行探讨。本文依据嘉陵江上游灵官峡河段(该河段河面窄,水深大,河段弯曲,床面粗糙,单式断面,在平面上断面变化较大)的模型试验资料,对目前常用的超高公式进行验算,在此基 I. Preface At present, there are quite a few formulas commonly used at home and abroad for calculating the ultra-high water level of river bends. Most of them are derived from standard curve test or purely theoretical deduction, which are not consistent with the characteristics of natural rivers and mountainous rivers. Bending water level calculation formula is discussed. Based on the model test data of the Lingguanxia reach on the upper reaches of Jialing River (the river has narrow river, deep water, curved riverbed, rough bed and single-section, the section changes greatly in the plane) Formula for checking, in this base
