【摘要】：通过采用长期预报和短期预报相结合的方式,准确预报尚家湾强岩溶隧道突水突泥伴生灾害源的规模与空间位置,结合超前钻探建立综合超前预报体系。针对发生的3次突水突泥灾害,通过现场踏勘和水文地质分析,查明突水突泥伴生灾害源的来源,揭示尚家湾隧道突涌灾害源的赋存特征、致灾模式及其致灾机理,提出突涌灾害是由压力水、泥砂相结合的伴生灾害源和突涌通道2部分组成,伴生灾害源是内在源动力,突涌通道是灾害源的优势运移路径。同时,建立集内外结合(隧道内部揭露围岩与地表环境)、综合预报、"循环推进,交叉评价"、动态补探、综合治理相结合的伴生灾害源探测及防治技术,提出相应的治理原则、治理方案及后续施工的预防措施。
[Abstract]:By using the long term prediction and short-term forecast method, accurate size and location prediction of SHANG Jia Wan strong karst water gushing disaster associated source, combined with advanced drilling to establish the comprehensive prediction system. According to the 3 water inrush and mud, through the field survey and Analysis on hydrogeology, identify the source water and mud bursting disaster associated sources, reveal the occurrence characteristics of SHANG Jia Wan Tunnel inrush hazard, disaster mode and damage mechanism, put forward by the pressure of water inrush disaster, mud and sand combined with associated disasters source and inrush channel 2 components, associated disasters source is the inner source of power. Water inrush channel is the dominant migration path of disaster sources. At the same time, establish a set of internal and external integration (inside the tunnel expose rock and surface environment), comprehensive prediction, "promote the circulation, cross evaluation, dynamic compensation, hazard detection associated with the combination of comprehensive treatment and The prevention and control technology, the corresponding management principles, the treatment plan and the follow-up construction prevention measures.
