Analysis on surrounding rock creep mechanism of TBM jamming
2013
Using international universal Burgur creep model,this paper calculated the quantitative relationship between jamming accidents and surrounding rock creep,deepen the understanding of TBM tunneling jamming mechanism in third series sandstone,pointed out in third series sandstone formation,because of the rock consolidation of rock difference,rock strength low,easy to be softened in water,so prone to jamming accidents.
