【Abstract】 Based on Erlang mountain road tunnel engineering practice,surrounding rock dynamic composite information of highway tunnel was obtained by routine surrounding rock deformation monitoring measurement,surronding rock deformation trace monitoring system and quadratic stress field measure.Dependable data was provided in surrounding rock class,large deformation and rockbust forecast as well as majorizing quadratic bearing time.Surrounding rock deformation is an important method of geotechnical engineering infomation design and construction.更多还原
