摘要
Abstract
The deformation law of loess tunnel surrounding rock in the process of tunnel excavation is known via the monitoring measurement of deformation of the kiln tunnel surrounding rock during construction.The arch settlement value is far greater than the clearance convergence value,so it is clear that the control of the large deformation of loess tunnel should be based on the arch settlement.The ultimate way to control the large deformation of loess tunnel during the construction process through the finite element:timely follow-up of primary supporting can significantly reduce the deformation of loess tunnel surrounding rock;pile treatment for loess tunnel foundation can effectively reduce the deformation of surrounding rock.The construction of system anchor bar has no impact on the deformation of surrounding rock basically.关键词
