摘　　要：在高压输电线路工程测量中,由于受植被影响,通视条件极差;常规测量方法不但赔偿费用高,而且工期长,测量工作量大,很难保证恢复后的直线与原直线一致。随着全球定位系统GPS(Global Positioning System)的广泛应用,可借助GPS定位技术方便、快速、准确地进行测量。本文论述的实时动态测量RTK(Real Time Kine2matic)智能定位系统,具有点、线、面之间相对关系的计算功能及直观的图形显示功能,实现了施工测量、记录、计算的高度智能化、一体化;与传统的测量技术相比,不受通视条件的限制,测量的距离远、速度快、精度高;在工程应用中可以显著地提高生产效率。In survey project of high voltage transmission line,due to effect of vegetations,the indivisibility condition is very poor; conventional surveying method results in not only a high cost,but also a long construction period and high surveying workload,therefore it is difficult to ensure the restored line to be in consistence with the original straight line. With the aid of GPS（ Global Positioning System） technology,survey project of high voltage transmission line can be accomplished conveniently,swiftly,and accurately. The real-time dynamic measurement of RTK（ Real Time Kinematic） intelligent positioning system discussed in this paper is characterized by its functions of calculating relative relationships among points,lines and surfaces as well as the function of visual graphical display, and is able to accomplish construction survey,record,as well as high intelligent and integration in calculation. Compared with traditional surveying techniques,it is free from constraints of visual conditions,and can be applied to long distance,while maintaining high speed and high precision. In general,real-time dynamic measurement of RTK intelligent positioning system can significantly improve the production efficiency in engineering applications.
