摘要

Similarity theory is used to model experiment for shallow-buried tunnel under the traffic load. Rules are developed for the tunnel lining stress and deformation; The results can be used to develop tunnel lining law of stress variability and the accumulative total effect of sedimentation by changing dimension, the amplitude, the frequency and the loading times with traffic load; At the same time, the feature changing rule can be obtained for the tunnel lining-destroying process through exerting limit load.
