In measuring Mazhu expressway Yibaokang tunnel vault and the surface subsidence, the project adopts total station triangle elevation method, the practice has proved that this method is not only rapid, efficient and reliable, its precision can fully meet the requirements of the construction. Using total station trigonometric apparatus to measure tunnel vault and the surface subsidence, the measured results can not only well reflect the basic trend of surrounding rock and soil mass in construction process, can also reflect the changes of the result affected by construction, these are all reliable basis of on-site construction and the evaluation of supporting stability.
