fx-4850 P计算器在威后水电站双曲拱坝测量放样中的应用

针对威后水电站抛物线双曲拱坝放样坐标计算的复杂性,根据多达19个计算式的相互关系,采用CASIOfx-4850计算器,编写了相应的计算程序;该程序能计算任意拱圈高程面上、中、下游任意放样边线点的设计坐标,为双曲拱坝施工放样提供了准确数据,提高了测量工作速度。

Application of fx-4850 P Calculator in Setting-out Survey for Double-curved Arch Dam of Weihou Hydropower Station

A calculation program is done on CASIOfx-4850 calculator based on the relationships of more than 19 formulas and the complexity in calculating the setting-out coordinate for parabolic double-curved arch dam of Weihou Hydropower Station,which can figure out the design coordinate of any setting-out sideline point of upstream,midstream and downstream at any arch ring elevation surface,and can provide accurate data for construction setting-out and raise the efficiency of surveying work.
