对于采用节段吊装法施工的拱桥,通常在施工前需计算节段吊点标高和预制胎架立模标高。经过对于平移曲线方程及其弧长积分方程的数学公式推导,以Excel下的VBA为平台,采用Romberg数值积分方式实现了批量坐标计算。其计算结果与CAD实绘图形查询结果一致,满足施工精度要求。该计算方法具有比CAD查询速度快、移植性强的优势,可为拱桥施工计算提供一定的便利。 For the construction of the arch with segment hoisting method, it is usually necessary to calculate before the construction segment lifting point elevation and the elevation of the preform model. After deducing the mathematical formula of the translation curve equation and the integral equation of the arc length, using Excel VBA as the platform, the Romberg numerical integration method is used to realize the batch coordinate calculation. The calculation results are consistent with the query results of CAD drawing graphics to meet the requirements of construction accuracy. The method has the advantages of quick query speed and high portability compared with CAD, which can provide some convenience for the calculation of arch bridge construction.
