Abstract
Type Ⅰ horseshoe cross-section with flat-bottom is a simplified form of the standard Type Ⅰ horseshoe cross-section. Because of its sim-ple cross section,it is a common type in the field of hydroelectric engineering. The normal depth solution involves high-order hidden equation,The traditional solving methods,such as trial method and chart method,are very complicated with low precision. In this paper,based on the mathemat-ics transformation for the basis equation,the explicit formula for the calculation of normal water depth of Type Ⅰ horseshoe cross-section with flat-bottom tunnel was derived by selecting proper variables and fitting curves. The maximum relatively error is 0. 472% under the general engineering design range. The characteristic of this formula is accurate and simple,which has great value for engineering application.关键词
