Research on the Application of Precision Engineering Measurement Technology in a Plateau Long Tunnel
With the rapid development of China's national economy and people's urgent demand for transportation,the plateau long tunnel project came into being.In order to meet the needs of engineering construction,how to accurately connect is the main technical problem faced at present.This paper takes a plateau long tunnel as an example,constructs a perfect plane coordinate system,and adopts the key technologies such as GNSS survey,data processing and precision analysis of control network,plane connection survey,traverse survey and network design and gyro directional survey.Using computer simulation to estimate the penetration error,guiding the design of the large tunnel control network,provides a strong technical support for the tunnel through,in order to provide reference and reference for similar projects.
