目前我国公路纵断图上竖曲线的设计绘制方法,一般是先定出切线后再插入竖曲线,并参考使用人民交通出版社出版公路技术资料七之“圆形竖曲线测设表”附图1为旧法之纵断面图。1953年苏联Н.М.安东诺夫提出“公路纵断面上竖曲线设计新法”一书(人民交通出版社出版,汪新宁译)。新法具有一定优点,但计算时间略长一些。曾在山东省丘陵区长80公里的某线试用新法设计,自制竖曲线模板亦不困难,试用的结果尚无很大困难之处。现公路总局设计文件示例中,指出一二级路竖曲线使用Н.М.安东诺夫新法设计,其他等级路线仍用旧法。旧法存在的缺点除王心方同志所述者外(见1957年第4期“公路”月刊),另一缺点是绘制纵断面图过于复杂。为改进目前纵断图上竖曲线计算绘制办
At present, the design and drawing method of the vertical curve of the longitudinal road profile in our country is generally to first set the tangent line and then insert the vertical curve. Reference is made to the “Vertical Vertical Curve Surveying and Mapping Table” with the publication of Highway Technical Information by People’s Communications Press 1 is the longitudinal section of the old law. In 1953, the Soviet Union Н.М. Antonov put forward the “Vertical Curve Vertical Design Road Law” a book (People’s Transport Press, Wang Xinning translation). The new law has some advantages, but the calculation time is slightly longer. In the hilly region of Shandong Province 80 km long trial of a new method of design, homemade vertical curve template is not difficult, the results of the trial there is no great difficulty. Now the highway design document example, pointed out that the use of Н.М. Antonov new curve design vertical curve, the other levels still use the old method. Disadvantages of the Old Law Except as stated by Comrade Wang Xinfang (see the monthly issue of Highway No. 4 in 1957), another disadvantage is that it is too complicated to draw a longitudinal section. In order to improve the current vertical line on the vertical curve calculation rendering office
