原文对双曲拱坝的薄壳理论分析法作了详细的研究,探讨了双曲拱垻的合理计算方程,并作出了实例计算。但有一些值得商榷的地方,今分数点说明如下。 (一) 双曲拱坝中面的几何性质比较接近锥壳或圆柱壳,对于这二类壳体(高斯曲率等于0)容易使第一、二次式系数(原文称拉姆参数)A=B=1。原文建议令双曲拱垻的A=B=1,这是一个重要的假定,它使计算方程得到了根本性的简化。
The original text of the double-curvature arch dam thin shell theory analysis method was studied in detail, discussed the rational calculation equation of the double curved arch, and made an example calculation. However, there are some areas that are worth discussing. The scores are explained below. (a) The geometry of the midplane of a double curved arch dam is relatively close to that of a conical or cylindrical shell. For these two types of shells (Gaussian curvature is equal to 0) it is easy to make the first and second coefficients (Lam parameters) A = B=1. The original suggestion is to make A = B = 1 for the double curvature, which is an important assumption, which fundamentally simplifies the calculation equation.
