Abstract

In order to reduce the monitoring error of vertical displacement and horizontal displacement in surface deformation, a regional surface deformation monitoring method based on GNSS and satellite signal processing is proposed. According to the basic principle of coordinate rotation transformation, the off set problem existing in the inflection point is adjusted at the same time to make the theoretical coordinate system rotate into the coordinate system in real mining. According to the GNSS and satellite signal processing results, the original working surface is adjusted to the calculated working surface to achieve the segmentation and prediction of the working surface and the monitoring of the regional surface deformation. According to
the engineering geological and hydrogeological conditions, NNBR model is introduced to measure and calculate the surface settlement due to the construction of tunnelling shield, and the design of regional surface deformation monitoring program is completed. The experimental results show that the monitoring value of the designed method is very close to the measured value of the vertical displacement, the monitoring error for surface horizontal displacement is low, and the monitoring value of regional surface settlement is basically consistent with the real value.
