随着交通事业的发展,公路建设工程日益增多,由于线路长、构造物多以及测量、施工要求质量高、时间紧等特点,传统的测量方法已不能满足新的要求,为此,迫切需要一种高精度、快速度、低费用、不受地形等条件限制、布设灵活的控制测量方法,GPS系统在这方面充分显示了它的优越性,因此在公路建设中得到广泛的应用。本文主要对GPS的特点及其在公路测量中的应用作了相关阐述。
With the development of transportation, the number of highway construction projects is increasing. Due to the characteristics of long lines, many structures, as well as high quality and time requirements of measurement and construction, the traditional measurement methods can no longer meet the new requirements. Therefore, there is an urgent need for a High precision, fast speed, low cost, free from terrain and other conditions, laying flexible control measurement methods, GPS system in this area fully demonstrated its superiority, it is widely used in highway construction. This article mainly elaborated the characteristic of GPS and its application in highway survey.
