20世纪80年代以来,我国高速公路得到了迅速发展,高速公路的建设也达到一个空前快速的阶段,这就要求工程建设部门能够快速的完成建设。在高速公路建设中测量放样工作是一切设计和建设工作的前提,如何快速的测量高速公路建设所需的测量数据事关整个工程的进度,而高速公路中线定测是整个测量工作的重点,传统的全站仪测量方式速度慢,且在高山树林地区测量开展困难。GPS-RTK技术是20世纪90年代中期发展起来的一种载波相位动态实时差分技
Since the 1980s, China’s expressway has been developed rapidly, and the construction of the expressway has reached an unprecedented rapid stage. This requires that the construction department can finish the construction quickly. It is the premise of all design and construction work to measure the setting-out work in expressway construction. How to quickly measure the measurement data required for highway construction is related to the progress of the entire project. The central line measurement of expressway is the focus of the whole survey. The traditional The total station measurement method is slow, and difficult to measure in the high mountain woods area. GPS-RTK technology is developed in the mid-90s of a carrier phase dynamic real-time differential technology
