随着我国经济的快速发展，越来越多的基础设施建设成为发展经济的前提，修建高速公路是基础设施建设的必要，如何高效率、高质量的完成高速公路的修建，成为测量工作人员需要解决的问题，而建立控制网则是保证工程质量的前提。越来越多的人选择使用GPS定位技术应用于平面控制网的测量工作中，那么GPS定位技术如何能够更好的发挥其在山区公路平面控制网中的应用，以满足较多较快的公路建设，使GPS技术越来越广泛的应用于公路工程中，成为现在社会发展、工程建设的需求。 本文简单的介绍了GPS定位技术中的测量原理、影响GPS测量精度的原因、论述了GPS控制网布设的原则，选点、埋石应注意的事项，介绍了GPS数据处理的过程。通过实例论述如何进行数据采集以及其作业要求，讨论了起算点对GPS数据处理的影响，网形对解算精度的影响，不同的数据处理软件的区别，以及最终结果精度的评定和分析对比。提出了在山区公路平面控制网过程中，应用GPS技术进行测量和解算时需注意的问题和解决问题的方法。

Along with our country economy fast development, the more and more many infrastructure construction into development economy premise, the construction highway is the infrastructure construction necessity, how does the high efficiency, high grade complete the highway the construction, becomes question which the surveying work personnel needs to solve, but establishes the control net is guarantees the project quality the premise.More and more many people choose use the GPS localization technology to apply in the plane control net surveying work, then how the GPS localization technology can better display it in the mountainous area road plane control net application, satisfy the many quick highway construction, causes the GPS technology more and more widespread application in the highway engineering, becomes the present social development, the engineering construction demand. In this article simple introduction GPS localization technology survey principle, has affected the GPS measuring accuracy the reason, elaborates the GPS control net build principle, the point sort, has buried the item which Shi Ying pays attention, introduced the GPS data processing process.Elaborates how through the example carries on the data acquisition as well as its work request, discussed has begun reckoning to the GPS data processing influence, mesh to resolved the precision the influence, different data processing software difference, as well as final outcome precision evaluation and analysis contrast.Proposed the question which using the GPS technology when the mountainous area road plane control net process, carries on survey and resolving must pay attention and solves the question method.
