Prediction and Analysis of Tunnel Crown Settlement Based on Grey System Theory

摘要

Monitoring measurement is of vital importance in mastering surrounding rocks dynamic, adjusting support parameters and determining reasonable supporting time in road tunnel construction using new Austrian method. The grey system theory can predict the development of surrounding rocks and the time required for the steady state by analysis and processing with a few original data. In this paper, the grey system theory was applied in the prediction of the crown settlement of Jiulianshan Mountain Tunnel and compared with the traditional regression analysis method. The results show that the grey system theory has great advantages in the prediction of the tunnel crown settlement.
