Abstract
In hydraulic engineering,it is common to encounter design parameters that are controlled by three factor variables:a categorical variable and two continuous data variables.Key interpolation points need to be determined by looking up a table and calculated using bilinear interpolation.In response to this issue,this paper used VBA for secondary development of Excel,and customized a function program using Excel VBA.The program can automatically determine the key interpolation points of design parameters based on the values of three factor variables,and complete the interpolation calculation of coefficients on this basis,achieving batch calculation of design parameters.The method is applied to batch solution of rainstorm point surface time chemical calculation coefficient in a river regulation project in Yunnan Province.The results show that the method solves the problem that the traditional manual table lookup is easy to make mistakes in solving the chemical calculation coefficient,and greatly improves the work efficiency.关键词
