摘要
结合贵阳轨道交通工程岩溶隧道施工中突泥、突水的工程实际,进行施工处理技术研究.从施工对策技术研究出发,分析了岩溶对隧道的影响,针对贵阳轨道交通工程1号线蛮坡站左线ZDK19+200处岩溶隧道发生突水、突泥进行处理,研究制订综合处理方案,提出并分析了封堵、引排和封排结合等3个方案,通过详细方案比选,确定封排结合方案最优,并设计制订了合理可行的封排结合方案和具体措施.最后,根据文献以及工程经验,总结了对于不同类型溶洞的处理方案,以期为类似工程提供借鉴.
Combined with Guiyang rail transit engineering karst tunnel engineering practice,carried out construction technology research.Based on the technical research of construction countermeasures,the influence of karst on the tunnel is analyzed,and the treatment of water inrush and mud inrush in the ZDK19+200 karst tunnel on the left line of Manpo Station of Line 1 of Guiyang Rail Transit Engineering is studied.The three options of plugging,drainage and combination of sealing and draining are analyzed.Through detailed comparison and selection,the optimal combination of sealing and discharging is determined,and a reasonable and feasible combination of sealing and discharging and specific measures are designed and formulated.Finally,based on the literature and engineering experience,the treatment schemes for different types of karst caves are summarized in order to provide a reference for similar projects.
