本文介绍了拱坝反力参数法的基本原理以及其计算机程序的功能与特点。文章从原理上阐明了反力参数法如何在提高计算速度的同时又能节约内存,从而做到在常用的微机上不使用外存而直接计算高密度的网格算题。反力参数法程序是我国拱坝设计中被推荐的四个多拱梁程序之一,已经在国内不少省区得到推广应用,文章介绍了反力参数法程序的各种版本的发展过程,并附有主程序框图以及适用于1988年微机版本的应用数据填法实例,可以作为希望掌握使用该种程序进行拱坝计算用户的入门参考。
This paper introduces the basic principle of the arch dam reaction force parameter method and the function and characteristics of its computer program. The paper illustrates how the reaction force parameter method can save the memory while improving the computing speed, so that it can directly calculate the high-density grid computing without using external memory on the common microcomputer. The reaction force parameter method is one of the four multi-arch beam programs recommended in arch dam design in China. It has been widely applied in many provinces and autonomous regions in China. The paper introduces the development process of various versions of the reaction force parameter method, Along with the main program block diagram and application data filling method for computer version of 1988, can be used as a reference guide for user who wants to master arch dam calculation using this kind of program.
