摘要
介绍了隧道防坍塌控制技术。隧道防坍技术依靠地下工程施工的经验,利用新技术的集成和优化,推行隧道防坍"二十四字"施工方针,灵活应用软弱围岩隧道施工"十八字"施工方针,贯彻"四项防坍基本经验",充分考虑地下洞室开挖支护的时间与空间效应,可广泛应用于公路隧道工程施工防坍。
Control technology of tunnel collapse prevention is introduced. Based on experience of underground engineering construction and utilization of integration and optimization of technology, tunnel collapse prevention technology carries out ＂ 24words＂ construction policy of tunnel collapse prevention, flexibly applies ＂ 18words＂ construction policy of weak surrounding rock tunnel construction, implements ＂ four basic experience of tunnel prevention which can , and adequately considerates excavation supporting time and spatial effects of underground caverns, be widely used in collapse prevention of highway tunnel engineering construction
