Based on references [1~3]. the mechanical models have been developed to study the presupport mechanism of forepoling bolt structure in this paper. The following problems are discussed:(1) the pre-support mechanism of forepoling bolt structure and stress distribution on its upper broken rock; (2) loading state of forepoling bolt; (3 ) solution of arching in the cross section of excavation. 展开更多
