On the basis of parameter sensitivity analysis, the simplified calculation formula is obtained by the regression method. 在参数敏感度分析基础上，利用回归分析方法求得裂缝宽度简化计算公式。
If the corresponding simplified formula can be derived, we can leave out the trivial detail of adjustment, so as to simplify calculation. 若能导出相应的简化公式则可以省去校正的繁琐，进而简化计算。
