摘要
介绍了基于Visual Foxpro编程实现利用实测大断面成果表生成左右起点距及面积表的情况。在确定左右起点距时主要考虑了当前水位与断面文件中相邻两个高程的几种关系,在计算面积时则考虑到了不规则河道的断面情况。经验证本文编制的程序所得结果完全正确,其中起点距和面积的小数位则结合新水文年鉴汇编刊印规范的要求来确定(也可以根据需要确定小数位)。另外本程序还能通过计算起点距进行断面数据的截取以便进行其他工程方面的利用。
The paper introduced the situation of using the measured results to form the area table and distance from intial point based on the Visual Foxpro programming.In determining the starting point it major considered the relationships between water level and the two adjacent elevation.In the calculation of the area,the irregulat section of river was considered.After the identification,the results of the program is completely correct,among them the fraction of the starting point and area is determined by the new hydrological yearbook assembly（can also be determined by the real）.In addition through the application of calculation of the distance from initial point,the program can carriy out the intercept of section data so as to apply other engineering.
