Abstract: Calculation formulas for the wave factor of hydraulics surface hole gate at Hedi reservoir given in Design Specification for Concrete Gravity Dam are analyzed. The calculations of mean wave height hm by using hypothesis method, successive approximation method and iterative method are complicated with big errors. In view of this, a convenient and accurate method of calculating mean wave height by using MathCAD software is given, and a formula for calculating the position of action point of the wave pressure is proposed. Calculation examples show that the calculation precision has increased by 75mm, and 10mm respectively than the other two methods. The wave pressure and its position of action point are also considered by this method, and the actual load of surface hole gate is reflected.

Key words: mean wave height, cumulative frequency, gate, position of action point, wave pressure
