Abstract

Abstract: This paper elaborates the judging methods and bases about surrounding rock deformation-crocking type and grade (i .e .collapse large deformation, gushing water-mud-sand which have something with the carbonatite predissolution actions, rockburst etc .)in the construction process of highway tunnel .The research results have important theoretical and practical significance to the informational construction and adopting advisable cure engineering measures in times

Key words: highway tunnel , surrounding rock deformation-cracking type and grade , judging method and basis , cure measure
