Establishment method and application of independent control network for extra-long tunnel in highway location survey
The establishment method of independent control network for extra-long tunnel in highway is introduced in this paper in detail.The impact of projection distortion on the accuracy of control point is reduced by changing the central meridian or projection plane.And the"one point,one direction"adjustment method is used to improve the accuracy within the control network.It is analyzed and explained for the practicality and efficiency of the proposed method in combination with the actual project situation.
