赵州桥净跨径考析

名闻遐迩的赵州桥是世界历史上最辉煌的土木工程范例之一。奇怪的是，作为此古桥最基本的技术数据的净跨径现尚无定论，众说纷纭。该文通过对著名建筑学家梁思成教授1934年撰写的赵州桥考察报告及其所附的实测图的研究分析，首次指出赵州桥的净跨径应为39±1米，现有的那些净跨径数字都不准确。该文建议挖开掩盖赵州桥拱脚的石块和泥土，找到两拱脚，精确测定净跨径。

Investigation and Analysis on the Clear Span of Zhaozhou Bridge

The well-known Zhaozhou Bridge is one of the most brilliant examples of civil engineering in the history of the world.It is quite strange that no final conclusion has yet been reached on the clear span of this ancient bridge as the most basic datum.Public opinions are divergent.Through studying and analysing the investigation report and the on-the-spot chart attached to it by the eminent building expert Prof.Liang Sicheng in 1934 on the bridge,this article points out for the first time that all available figures about the clear span of the bridge are not accurate,which should be 39±1 meters.The article proposes to clear away the earth and stones covering the two springs of arch of the bridge and then survey and determine with accuracy its clear span .
