Study on the Relationship between Stress-Deformation and Space-Time in Hejiagou Tunnel Construction

Abstract:

Based on the technological features of highway tunnel information design and construction，the relationships between stress-deformation and space-time were studied profoundly, combining closely to the monitoring practice of Heijiagou highway tunnel in Beijing to Chengde express way. With the results in rock mass stress monitoring, the adjustment law of stress was analyzed; and the relationships among stress and rock mass classification, burial depth and geologic conditions were disclosed. A profound study about the features of the relationship between rock mass deformation and space-time was carried out, as well. Finally, the application of monitoring results on rock mass classification, hazard forecasting and determination of the best time to construct the secondary supporting was introduced.
