Research on measurement technology and method of railway CP Ⅲ network construction
The low precision control network of ordinary railways can not meet the needs of railway operations and maintenance in the new period.It is of great significance to reconstruct the control network of ordinary railway by using the control and measurement system of foundation pile control network(CP Ⅲ).In order to study the CP Ⅲ measurement technology and method,this paper takes a railway reconstruction project as an example,introduces the railway control network layout requirements,and introduces the technical methods of CP Ⅲ encryption survey,plane survey and elevation survey in detail.The results show that the control indexes of the network construction survey meet the requirements of the code,and the research content can provide reference for related engineering applications.
