摘要
云雾山隧道在施工过程中揭示多处大规模岩溶。本文对云雾山隧道溶腔的综合施工技术进行了系统的论述,包括超前地质预报、注浆加固、爆破放水和加强支护等施工技术。该施工技术在该段溶腔的成功应用可为同类型溶腔处理提供经验和借鉴。
Several large cavities were revealed in the constructions of Yunwushan tunnel. This article systematically describes the comprehensive construction techniques of cavities in Yunwushan tunnel, including the geologic forecast, grouting reinforcement, blasting &water-drainage and reinforced support. The construction techniques applying to these cavities successfully can provide experience and reference for the same type cavities.
