隧道富水断层破碎带常发生突水突泥灾害,给施工安全带来极大威胁,需要制定一套能有效降低灾害影响的处治技术和超前地质预报对策。结合北岭山隧道工程实例,首先从地质条件和施工组织两方面分析突水突泥灾害形成原因,然后根据工程类比和经济技术比选,确定采取堆渣挡护、注浆加固、塌腔回填、小管棚进洞等处治措施,最后,针对富水断层破碎带地质特性,通过研究比较几种常用的地质预报技术,提出由TSP与地质雷达联合探测、超前水平钻孔辅助探水相结合的综合地质预报对策,所得结论对类似工程具有一定的借鉴和指导意义。
Water and mud-rock disasters often occur in the fractured water-rich tunnels of the tunnel, posing a great threat to construction safety. Therefore, it is necessary to formulate a set of treatment technologies and advanced geological prediction measures that can effectively reduce the impact of disasters. According to the engineering example of Beiling Mountain Tunnel, the causes of water inrush mud disasters are firstly analyzed from geological conditions and construction organization. Then, according to engineering analogy and economic technology comparison and selection, it is determined to adopt dreg slag protection, grouting reinforcement, , The tunnel shed into the hole and other treatment measures. Finally, in view of the geological characteristics of the fractured zone of the Fushui fault, by combining several commonly used geological prediction techniques, it is proposed that the combined detection of TSP and GPR and the combination of advanced horizontal drilling with water exploration Comprehensive geological forecasting strategies, the conclusions obtained for similar projects have some reference and guidance.
