Establishment and Innovation of High Speed Railway Engineering Survey System

The establishment of high speed railway engineering survey system provides technical support for the construction of world-class high speed railway in China.This paper reviews the methods and characteristics of the establishment of engineering survey system for high speed railway in China,and analyzes the problems in the standard system,such as the narrow scope of application,the difficulty in restoring the shape of control survey network,the unreasonable index of satellite positioning survey,the imperfect judgment standard of control network resurvey,the unclear principle of resurvey results and the contradiction between them,and briefly introduces some technical innovations of high speed railway engineering survey and puts forward the suggestions on optimization of technical standards and continuous construction and innovation of high speed railway engineering survey system.
