摘要： 隧道开挖过程中，塌方时有发生，特别对于深埋隧道紧急停车带位置的施工，塌方发生的概率会更大。以羊八井1号隧道在2018年12月4日发生的塌方事故为背景，根据现场塌方情况及勘测资料，对塌方段提出了加固方案，通过分析得出：雷达跟踪塌腔加固施工，可避免由于施工不合理的二次塌方；此工程加固方案的设计和施工，可为类似塌方工程加固方案提供借鉴。

Abstract: The collapse hazards are frequently encountered in the tunnel excavations, especially, in the emergency stopping zone. The economical and life loss induced by these failures are often huge and the even uncountable. This paper presents a case history of remediation of the collapse at Yangbajing No. 1 Tunnel on December 4th, 2018. The reinforcement method was able to be proposed based on the collapse and geotechnical and geological information at the site. The following measures were used during the remediation: the ground penetrating radar was used to control the quality of the construction in the collapsed zone so that the following collapses were avoided.

Key words: Collapses, Caved Cavity, Remediation Methods
