Influence Analysis of Ground Asymmetric Load to the Surrounding Rock Pressure of Existing Open Trench Tunnel
Based on the Protojiakonov's theory and Rankine's earth pressure theory, the existing open trench tunnel under ground asymmetric load, the failure mode of the surrounding rock and the calculation of the surrounding rock pressure will be analysed in this paper. According to the buried depth, the analysis shows that the surrounding rock pressure calculation can be divided into three situations: when the tunnel is deep buried, the Protojiakonov's theory is used to calculate the surrounding rock pressure; when the tunnel is shallow buried and the side wall generate soil arching effect, the surrounding rock pressure calculation of the side wall will consider the soil arching effect and use the Protojiakonov's theory. However, another side wall will use the Rankine's earth pressure theory; when the tunnel is shallow buried and the side wall can't generate soil arching effect, regarding the two side walls as retaining walls according to the Rankine's earth pressure theory.
