一、引言 近年来,应用电子计算机对混凝土坝的各种内部观测资料的分析已有不少资料。本文主要在文献的基础上作进一步的理论分析,扩大它的应用范围,从数学上证明混凝土坝应变计测值的应力用变形法与松弛法计算是完全一致的;所提供的公式克服了变形法计算繁琐的缺点。只要徐变函数等初始资料提供得确切,可以很方便地在电子计算机上进行应力计算,在实际应用中比松弛法有较大的优越性。
I. INTRODUCTION In recent years, there have been many data on the analysis of various internal observation data of concrete dams using electronic computers. This paper is mainly based on the literature for further theoretical analysis to expand its scope of application, from the mathematical proof of concrete dam strain gauge stress calculation method with deformation and relaxation method is completely consistent; provided by the formula to overcome the deformation Law calculation cumbersome shortcomings. As long as the initial data such as creep function are provided exactly, the stress calculation on the computer can be carried out conveniently. Compared with the relaxation method, it has great superiority in practical application.
