Theory and practice have proved it is easy to happen collapse when there are lining back cavities in tunnel. Therefore, if there is overbreak during tunnel construction, it is obligatory to infill the overbreak. If construction can be carried out rationally according to dynamic montoring and control, this kind of collapse can be avoided.
