The Lining Pressure of Bedding Rock Jointing Tunnel Distribute Characteristics

This paper studies the stress distribution of tunnel support, the mechnical behavior of the bedding jointed rock mass was analyzed. The influence to the lining structure was also analyzed. According to the calculations of FLAC3D, the numerical modelling analysised the prejudical pressure of the lining structure. On the basis of the analysis of the test data, it showed the characteristics of the earth pressure around section, and the relationship between different dip angle of the bedding rock jointing. All these works were beneficial for the supporting form and the method to the bedding rock jointing tunnel.
