摘要
TBM工法对地质条件要求较高,山区往往地层情况复杂,隧洞施工过程中易遭受围岩破碎变形、失稳坍塌、涌水、岩爆等突发状况.以南水北调安阳市西部调水工程输水隧洞为例,分析了该工程隧洞施工过程中的不良地质条件,并根据现场情况结合工程经验,提出了针对性的应对措施,可供类似工程进行技术参考.
Abstract
TBM method has high requirements for geological conditions,and the strata in mountainous areas are often complex.During tunnel construction,sudden situations such as surrounding rock fragmentation,deformation,instability,collapse,water inflow,and rock burst are prone to occur.Taking the water transfer tunnel of the West Water Diversion Project in Anyang City of the South-to-North Water Diversion Project as an example,the unfavorable geological conditions of the tunnel construction process are analyzed inthis paper.The targeted countermeasures based on the site conditions and engineering experience are proposed.It can offer technical guidance for similar projects.
