用补正系数法计算多跨索道悬索张力的探讨

日本加藤诚平教授所建立的悬索张力设计法的应用条件与我国林业多跨索道的型式存在着不相适应。本文在分析的基础上,遵循加藤氏等人补正计算理论的主导思想,导出能适应我国林业索道型式的任意跨数索道悬索张力计算方法及计算公式。 在我国林业多跨索道设计应用中,本文提出的悬索张力计算式使加藤氏法具有与苏联杜盖尔斯基教授的设计法相同的计算精度。

DISCUSSION ON HOW TO CALCULATE A MULTI-SPAN AERIAL CABLEWAY BY THE CORRECTION FACTOR METHOD

The design method of an aerial cableway, established by professor Kato Seinei in Japan, is one of the design methods adopted by the logging engineers in China. But his method is not suitable for calculating the tension in the skyline of a multi-span aerial cableway in China because the results are not accurate enough for unloaded spans under certain conditions. His method, therefore, has not been widely used in China. The author discusses in the text why this method is not suitable for calculating the multi-span aerial cableway in China , and then derives formulae suitable for this purpose from the correction theory established by Professor Kato et al. This makes this design method, when used for calculating a multi-span aerial cableway, have the same accuracy as the method established by professor Dugalski in Russia.
