摘　　要：为了更好地保证铁路隧道施工质量、安全,对隧道施工中炭质板岩溜塌处理措施进行研究。施工中因地质构造、形式、特点、施工措施等原因,会导致隧道施工中面临初期支护变形塌方、掌子面溜塌、溶洞和滑层等。通过对花椒坡隧道施工中出现的溜塌形式和处理措施进行分析和研究,总结出回填反压、封闭溜塌体厚度15 cm、采用?76中管棚注浆等处理措施,最终取得了良好的处理效果。The treatment measures for carbonaceous slate collapse in tunnel construction is researched in order to better ensure the quality and safety of railway tunnel construction. Some problems such as deformation and collapse of initial supports, tunnel face collapse, karst caves and parietal callus may be caused by the structure, form and characteristics of geology, construction measures and other reasons in tunnel constructions. Therefore, this thesis summarizes some treatment measures such as counter-pressure backfill, setting closed landslide body as a thickness of 15cm and grouting with 76 medium pipe-roof through analyzing and researching collapse forms and treatment measures in the construction of Huajiaopo Tunnel, which finally achieve good treatment effects.
