一、原文中存在的问题 潘家铮同志“弹性地基上圆拱的计算”(见本学报9卷2期)一文,对弹性地基上圆拱的计算作了较全面的分析,推导了形常数和部分载常数,在许多情况下引用杆件常数的概念以节点的变位作未知数利用形变法去解弹性地基上的圆拱结构物,这是极其简捷的方法,但原文在推导形常数和载常数中引用了粗略的角变位(用符号?代表)关系: I. Problems in the original text Comrade Pan Jiaxuan wrote “Computation of Circular Arches on Elastic Foundations” (see the volume 9 of Vol. 2 of this paper). It gives a more comprehensive analysis of the calculation of circular arches on elastic foundations and derives the shape constants and parts. The constant of load, in many cases the concept of the reference rod constant uses the deformation of the node as an unknown to use the deformation method to decompose the circular arch structure on the elastic foundation. This is an extremely simple method, but the original is deducing the shape constant and the constant of the load. A rough angular displacement (represented by the symbol?) relationship is quoted in:
