To realize continuous ultrashort
edge traverse measurement in tunnel and select an appropriate measurement
scheme, a case study is conducted on an inclined shaft of seacrossing tunnel of Qingdao metro. Multiple traverse measurement
methods such as conventional double traverse measurement, virtual double traverse
measurement, side intersection traverse measurement with multiturning points, corner intersection traverse measurement with free
station and multipublic points, and conventional
double traverse measurement + gyro composite directional measurements are
applied in the project. The application conditions, measurement efficiency, and
effects of various methods are compared and analyzed, and the best measurement
results are used to guide the construction of crosssea
tunnels, so as to ensure the high precision of tunnel penetration. The
advantages, disadvantages, and application conditions of these measurement
methods are summarized, providing guidance for traverse measurement inside
tunnel without help of gyroscope.
