摘　　要：基于正交异性板法原理,从理论上推导了荷载作用下的横向分布表达式,并采用分段函数对其进行拟合;不仅提高了计算效率,而且精度大大提高;同时推导的横向分布表达式还可用于模块化编程,为工程软件分析提供基础。Based on the analogy orthotropic plate principle,traverse distribution function under the design load is theoretically deduced and the piecewise function to fitting curves is used.This computation method has greatly improved not only the computational efficiency but also the precision.Furthermore,the deduced transverse distribution expression is also available to be applied in the modular programming,which has laid a foundation work for the engineering software analysis.
