Analysis of collapse treatment in highway tunnel with eztra-large cross-section and cow flat-ratio
During construction of extra-large cross-section and cow flat-ratio highway tunnel, collapse accident of the core soil occurred. According to the field geological and construction conditions, the numerical model is set up and the commercial software Tongjishuguang is adopted to simulate the behaviors of the tunnel and surrounding rock. Based on the results of plastic zones in surround rocks, deformations in rock and lining, and the inner forces within rock bolts and reinforced concrete lining, the deformation of the tunnel and the causes of tunnel collapse are analyzed. The corresponding effective remedy measures are proposed; and good results are achieved.
