Abstract:
Large deformations are liable to occur for a double-track railway tunnel with large profile passing through carbonaceous slate stratum. Based on the engineering practice and experiments, the paper analyzes the mechanism of deformation evolution on carbonaceous slate sections and various impacting factors in terms of geological conditions, underground water, support parameters and construction technology. Furthermore it puts forward measures such as optimization of support parameters, structural deformation control by anchor bolt and grouting.
