Rebound Control Method of Buried Tunnel

摘要

We have taken notice of the buried tunnel deformation for heaving under the bottom of the excavation. Especially the both ends of the excavating area are more important for the winding of the buried tunnel. We have developed a new Rebound Control Method to reduce the wind of buried tunnel. This paper shows the new idea as the deformation control measure to the buried tunnel, the result of predicted rebound value by FEM, and the suitability for the new idea by using the observational method.
