黄文熙教授提出的格栅法,可以适用于求解拱坝、板壳等结构。尤其在拱坝的计算中,更有优于其它方法(诸如试载法、有限单元法等)之处,故应予推广使用。本文在力求领会格栅法之精华的同时,就其中的一些计算方法进行了讨论,研制了格栅法计算拱坝等结构的静力、动力分析程序。通过几个例题的计算证明,格栅法在拱坝计算中确有很大的优越性;并由此计算成果分析得出了格栅法用于拱坝计算中的初步结论。
Prof. Huang Wenxi’s proposed grille method can be applied to solving arch dams, plate shells and other structures. Especially in arch dam calculations, it is better than other methods (such as trial load method, finite element method, etc.), so it should be promoted and used. While trying to grasp the essence of the grid method, this article discusses some of the calculation methods and develops a static and dynamic analysis program for calculating the arch dam and other structures using the grid method. Through calculation of several examples, it is proved that the grid method has great advantages in the calculation of arch dams; and from this calculation results, the preliminary conclusions of the grid method used in arch dam calculation are obtained.
