拱坝是一种比较节省的坝型。近年的理论研究和建设实践表明,拱坝对地形地质条件的要求已逐步放宽,适应能力有所提高,在我区具有广泛的发展前景。因此,编制拱坝应力计算优化程序,对促进我区拱坝建设具有现实意义。我们从这一需要出发,选择了具有较高计算精度和效率的“三点双调法”为应力分析的基本方法,应用满应力原理,结合坝肩稳定分析(刚体极限平衡法)。编制了拱坝优化程序。这一程序先用 ALGOL语言编成,在 TQ—16机上计算。1984年投入使用,先后已计算所略水库、青背水库、
Arch dam is a more economical dam type. In recent years, theoretical research and construction practice show that the requirements of arch dam on topographic and geologic conditions have gradually been relaxed and the adaptability has been raised, which has a wide range of development prospects in our region. Therefore, the preparation of arch dam stress calculation optimization program, to promote the construction of arch dam in our area has practical significance. Based on this need, we choose the “three-point double-tuning method” with higher calculation precision and efficiency as the basic method of stress analysis, and apply the principle of full stress, combined with the stability analysis of dam abutment (rigid body limit equilibrium method). Arch dam optimization program has been prepared. This procedure was first compiled in ALGOL language and calculated on a TQ-16 machine. Put into use in 1984, has been calculated slightly reservoir, green back Reservoir,
