桥梁荷载横向分布比拟正交异性板法的电算方法探讨

Probing into Computation Method of Guyon-Massonnet for Bridge Loading Transverse Distribution

比拟正交异性板法,即G-M法,是目前确定桥梁荷载横向分布系数的一种常用方法。但是该方法计算过程繁冗,具有重复性,而且它所用到的计算图表粗略,每次所查读的影响系数K0和K1值都是估读,误差较大。该文通过运用多种计算机软件,整合G-M法的计算过程,使之快捷准确。并举例说明,可供桥梁设计人员参考。

The Guyon-Massonnet method, that is G-M method, is a common method to determine the bridge loading transverse distribution coefficient now. But the calculation process of this method is lengthy and tedious with repeatability, and its used calculating charts are rough. The checked and read influence coefficients of K0 and K1 values are all estimated to read every time. Its error is larger. Through applying many kinds of the computer software, the article fits with the calculation process of G-M method to make it quick and correct. The example is taken to the bridge designers for reference.
