A Precise Surveying Network Establishing Method for Existing Line Deviation Control
摘要
Abstract
With the control of existing railway line in China for absolute position and the reference to high-speed rail CPIII with free-station linear-angular Intersection, this article puts forward a precise line deviation control surveying network to maintain absolute position of existing railway line. And detailed discuss on the net program, the measuring method, the coordinate transformation between adjacent station lap and the analysis of existing problems are conducted. This network, using unilateral control network, is easy to be established with low cost, and it can be used in v-shaped skylight period. It employs total station instrument for direct measurement with high efficiency. The results show that the precise deviation constrain surveying network can be extensively used as a new type of track control network for absolute position control of the existing railway line.关键词
