摘要
为了分析双护盾TBM施工隧道超前地质预报技术的应用效果,通过对双护盾TBM的施工环境的分析,明确TBM施工隧道地质预报工作的难点。采用被动源HSP法、主动源ISP法和RTP法进行西藏DXL隧道的综合预报,并结合案例,分析了综合预报技术在双护盾TBM中的探测效果。结果表明,通过被动源HSP法、主动源ISP法探测掌子面前方地层构造界面分布位置与规模,辅以RTP法探测异常区富水特性,能较好地实现双护盾TBM施工隧道前方不良地质体的预报,有效地指导施工。
In order to analyze the application effect of advanced geological prediction technology in double shield TBM tunnel construction,this paper clarifies the difficulties of geological prediction in TBM tunnel construction by analyzing the construction environment of double shield TBM.The method of HSP,ISP and RTP has been applied to the DXL tunnel in Tibet.Combined with the case,the detection effect has been analyzed in comprehensive prediction technology in TBM with double shields.This paper adopts the passive source HSP method and active source ISP method to detect the location and scale of the geological structure interface in front of the face of the tunnel,and the RTP method to the water-rich characteristics in the abnormal area as a supplement,which can better achieve the prediction of the unfavorable geological body in front of the tunnel constructed by double shield TBM and effectively guide the construction.
