Abstract:

On basis of the insitu monitoring results and the measured data of ground pressure,  primary reinforcement stress and structure internal force, the pattern of the huge deformation of the soft ground in the extremelyhigh groundstressed portion of Baozhen tunnel is analyzed and the corresponding construction parameters are timely adjusted, which guarantees the construction safety.
