Abstract：Research purposes: The systematic review and analysis are made for the development experience of survey technology for railway construction since 1949，the situations and problems are described in the aspects of engineering survey，aerial survey ， physical measurement ， probing and in site measurement of survey technology for railway construction，and the development future is prospected systematically and comprehensively for the aspects mentioned above of survey technology for railway construction.
Research Conclusions: The surveying devices will become lighter and integration with higher accuracy，more functions， easier operation，and digitisation ， modularisation and automation to collect and process the data. It is the general development trend of the survey technology for railway construction to establish construction survey and design data bank and improve the applicable mode of “Integration and Intellectualization” for railway survey and design in order to meet the requirements for more and more construction of high一speed railway and passenger dedicated railway line crossing and sea.
