VFP测量数据库应用系统开发

摘要随着城镇化和低碳交通的推进，地铁建设正如火如荼的进行着。联系测量作为地铁建设中必不可少的工作环节，正发挥着越来越重要的作用。本文根据竖井联系测量原理，以Visual FoxPro6。0为开发平台，设计完成了测量数据库应用程序。本程序兼顾了联系测量的内业数据计算、成果入库及数据查询。其中，竖井平面联系测量采用一井定向和陀螺仪定向两种方法，高程联系测量采用长钢尺法导入高程。另外，本程序也包含角度互化、坐标正反算、高斯投影正反算和子午线收敛角计算等程序，以作为联系测量计算程序的辅助工具。73424

Development of Database Application System Based on the Measurement of VFP

Abstract Along with the advancement of urbanization and low-carbon transportation, subway construction is in full swing。 As an indispensable part of the subway construction, connection survey is playing a more and more important role。In this paper, according to the principle of the shaft connection survey, FoxPro6。0 Visual is used as the development platform, and the database application program is designed。This procedure can be used to calculate the internal data of connection survey, can also put the results in storage, and can query the calculated data。Among them,the shaft plane connection survey uses two methods, single shaft orientation and gyrostatic orientation。And levation connection survey uses the method of suspended steel tape。In addition, the program also includes four small programs, as a supplementary program for the connection survey。 They include angle interaction,coordinate positive and negative calculation ,gauss projection positive and negative calculation,and meridian convergence angle calculation。

This paper has 21 figures, 5 tables, 8 references。
