卵砾石层中公路隧道设计与施工技术分析

Design and Construction Technology of Highway Tunnel in Gravel Deposits Layers

目前国内外隧道工程多建设在岩石或土层之中,而在卵砾石层中修建隧道的案例较少,其设计、施工均缺乏足够的经验与技术,在分析卵砾石层工程特性的基础上,探讨其设计、施工、监测的关键技术要点,对日后该种特殊地质条件下的隧道规划、设计与施工都具有参考意义。

Most of tunnels are constructed in rocks or soils, however, the gravel tunnels are seldom encountered. Thus, the experience for gravel tunnel design and construction is still lacking. According to the studies on the characteristics of the gravel deposits layers, carrying on a discussion on the key points of design, construction and survey technology can gives reference for tunnel design and construction in the similar geological conditions in the future.
