摘要: 围绕表孔水工闸门波浪要素的计算,在依据《混凝土重力坝设计规范》给出的鹤地水库计算公式,分析了现行采用假设、逐步逼近、迭代等计算方法计算平均波高hm时存在的计算繁琐、误差大的问题,利用MathCAD软件给出了计算简便、结果准确的平均波高的计算方法,提出了波浪压力作用点位置的计算公式,并进行了具体的算例分析。结果表明,该方法较文献[4]提出的《土石坝规范》方法、《荷载规范方法》,计算得出的平均波高hm的精度分别提高了75,10 mm。计算波浪压力时综合考虑了其大小和作用点位置,更为真实地反应了表孔闸门的荷载。

关键词: 平均波高, 累积频率, 闸门, 作用点位置, 波浪压力

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
