摘要
数值分析的结果通常不便于工程直接应用,需要回归成解析形式,回归公式不仅在精度上要满足工程需要,而且在量纲上应符合和谐原理。文章通过对现行水泥路面设计规范荷载应力计算公式的量纲进行分析,从量纲和谐原理对公式提出了修改建议。
In engineering community,the regression formula were popular than the direct results of numerical analysis.But the analytical formula must be both accurate and accord with Dimension Concordant Principle.The stress formula in Specifications of Cement Concrete Pavement Design was analyzed,and the suggestions to modify the stress formula were given by Dimension Concordant Principle.
