Method and system for quantitatively evaluating engineering quantity of overhead transmission line

The invention provides an overhead transmission line engineering quantity quantitative evaluation method and system. The method comprises the following steps: obtaining tower data of a to-be-predicted case; substituting the tower data of the to-be-predicted case into a pre-constructed regression model to obtain the engineering quantity of the to-be-predicted case; wherein the pre-constructed regression model is obtained by performing regression analysis by adopting a multiple linear regression method based on tower data and engineering quantity in historical cases. According to the method, by establishing the regression model, a designer is helped to predict the accurate engineering quantity with few input conditions, the calculation amount in the engineering quantity prediction process is reduced, and the number of influence factors is reduced. 本发明提供了一种架空输电线路工程量量化评估方法及系统，包括：获取待预测案例的杆塔数据；将所述待预测案例的杆塔数据带入预先构建的回归模型中，得到所述待预测案例的工程量；其中，所述预先构建的回归模型是基于历史案例中的杆塔数据和工程量采用多元线性回归方法进行回归分析得到的。本发明通过建立回归模型，帮助设计人员以较少的输入条件预测较为准确
