高压、富水岩溶隧道施工地质预报探讨
Study on Geological Prediction for a High Pressure Water-soaked Karst Tunnel
【摘要】 在新大瑶山隧道工程中,建立了隧道施工地质预报机构和地质信息系统,采用了宏观控制预报、准确预报、验证预报三级预报方法。由于利用了以野外地质调绘、洞内CCD地质编录、超前水平钻探、TSP203及直流电法为主要探测手段的综合预报技术,提高了预报的科学性、准确性,降低了预报成本。
【Abstract】 In the new Dayaoshan tunnel project,tunnel construction geological prediction agencies and geological information system were established which incorporated three-phase macro-control,accurate and validatation forecasting.In the process of construction a comprehensive geological prediction process was adopted including field geologic surveying and mapping,CCD geological logging,advance horizontal drilling,TSP 203,DC methods,which improved the forecasting accuracy and reduced the cost of prediction.
