| 摘 要： | 理论和实践都证实了,隧道衬砌背后存在空洞时,易引起隧道塌方等灾害。因此,在隧道施工过程中,如遇到超挖的情况,一定要把衬砌背后的超挖部分填实,并能根据动态监控量测,进行规范施工,以避免类似的塌方事故。

| Abstract: | 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. |
