Research on Deformation Damage in Shallow Buried and Unsymmetrical Loading Loess Tunnel's Port and Remedial Measures |
| |
| Abstract: | Taking the construction of a loess tunnel for example,the cause of deformation damage and the remedial measures in the shallow buried and unsymmetrical loading loess tunnel's port are analyzed when excavating, and the anchor grouting method and interval excavation technology are suggested here,so as to reduce the disturbance to surrounding rocks,strengthen the measurement and the dynamic monitoring for the whole process,and solve the problems in construction.The results show that the measures are effective in rock deformation control. |
