一、前言 拱坝的应力计算一直是一上困难的问题。设计工作者要求一个比较简单而又相当准确的计算方法。试载法的计算程序过于复杂,纯拱法和拱冠梁法又过于粗略不够准确,而利用壳体理论的计算方法还不够成熟,有待研究。本文的目的,是在拱冠梁法的基础上,改进计算程序,并考虑更多 I. INTRODUCTION Stress calculation of arch dams has always been a difficult problem. Designers demand a relatively simple and fairly accurate calculation method. The computational procedure of the trial loading method is too complicated. The pure arch method and the arch and crown beam method are too rough and not accurate. However, the calculation method using the shell theory is not mature enough to be studied. The purpose of this paper is to improve the calculation procedure and consider more on the basis of the crown and beam method.
