本文介紹蘇聯計算木橋面所用的載重彈性分佈理論和應用,對公式中的分佈係數的來源,加以演證。在證明公式的同時,使用了為蘇聯學者所創造並被廣泛採用來計算超靜定問题的方法——原始參變數計算法。文內並述及公式的應用。給出中梁和邊梁上載重分佈計算,及如何晝影響綫。除汽車載重的彈性分佈外,更說明了履帶車均佈載重如何驗算,這些是最近實用上常遇到的問題。
This paper introduces the theory and application of the elastic load distribution used by the Soviet Union for calculation of wooden decks, and gives a demonstration of the sources of distribution coefficients in the formula. At the same time as the formula was proved, a method for calculating the statically indeterminate problem created by Soviet scholars and widely adopted was used—the original parametric variable calculation method. The article also mentions the application of formulas. Give the calculation of the redistribution of the middle beam and the side beam, and how to use the influence line. In addition to the elastic distribution of the vehicle’s load, it also explains how the uniform weight of the crawler vehicle is checked. These are problems that have recently been encountered in practice.
