本文在试载法的基础上加以发展改进提出一种新的拱坝动力与静力分析的多拱梁法.方法的要点是将拱坝离散化为一系列拱或梁单元,以此作为基本计算单元建立体系的动力或静力方程,同时利用单元的模态函数作为基向量进行坐标变换以使方程的自由度数得到高度节约,使计算大为简化.方法在微型计算机上得到了实现,它具有功能比较全面、输入信息简便,所需内存容量小,节约计算机时,并达到良好精度等特点.
In this paper, based on the test method, a new multi-arch beam method for dynamic and static analysis of arch dam is proposed. The main point of the method is to discretize the arch dam into a series of arch or beam elements, The calculation unit establishes the dynamic or static equation of the system and at the same time makes use of the modal function of the unit as the basis vector for coordinate transformation so that the degree of freedom degree of the equation is highly conserved and the calculation is greatly simplified.The method is implemented on a microcomputer, Has a more comprehensive function, the input information is simple, the memory required small, save the computer, and to achieve good accuracy and so on.
