摘要
在900余组次水力模型试验的基础上,对现行铁路八字翼墙进口盖板箱涵及拱涵定型图正交和斜交涵洞水力特征值选用的可靠性及合理性进行了验证;对涵洞设计中采用的计算方法提出了修改建议;提供了涵洞水力计算方便可行的经验公式;讨论了自行设计的斜交涵洞与定型图正交涵的关系。
Based on the results of 900 and more hydraulic model tests,the reliability and rationalization of the hydraulic parameters, for both normal and skewed culverts, given in the standard drawing of railway box and arch culverts with import from splay flank walls,have been verified. A proposal concerning the modification of the calculation method used in culvert hydraulic designing is described, and a convenient approximate formula for the culvert hydraulic calculation is developed. The relations between skewed culverts designed of one's own and normal culverts given the standard drawing of railway are also discussed.
