%X 以某公路隧道塌方为工程背景，分析塌方发生原因，得出该塌方发生的原因为地质原因，进行浅埋大断面隧道塌方处置措施分析，包括测量放样、洞内反压回填、洞顶开挖及边坡支护、拱顶浇筑及初期支护、洞身开挖及支护、洞顶基坑回填压及实施工要点和注意事项、安全保障措施等。结果表明，该塌方处置措施效果显著，可为类似塌方处置提供参考。<br />
Taking the collapse of a highway tunnel as the engineering background, the paper analyzed the cause of the collapse for shallow buried large-section tunnels, concluded that the cause of the collapse was the geological cause, and analyzed the collapse disposal measures, including measurement and lofting, hole counter-pressure backfill, cave roof excavation and slope support, vault pouring and initial support, cave excavation and support, cave body excavation and support, cave top foundation pit backfill and implementation of key points and precautions, safety and security measures, etc. The results show that the landslide disposal measures are effective and can provide a reference for the similar landslide disposal.
