Abstract:Abstract:Research purposes: High geothermal disaster was encountered during the construction of 4 deep-buried long tunnels of Daiyun Mountains tunnel group on Xiangtang-Putian Railway. A special method for original geothermal test in deep-buried long tunnel was proposed. And the accuracy of this method was verified through the comparison and analysis of the measured temperature of tunnel during construction with the ground temperature obtained by comprehensive logging prediction during the investigation.
Research conclusions:(1)Through drilling horizontal deep boreholes, installing temperature test probes, grouting the deep borehole, geothermal testing and long-term observation, the original geothermal data were obtained. (2)The predicted maximum geothermal value was smaller and the geothermal range was narrower than the site observed values. (3) The geothermal gradient prediction values of deep buried tunnel in Fujian were about 3~4 ℃/100 m for the stage of prefeasibility and feasibility study, while 1.5 ~ 2 ℃/100 m should be increased for the stage of preliminary design and construction drawing stage. (4) The research results can improve the accuracy of geothermal prediction during the investigation and can be referenced for railway, highway and other deep buried underground engineering projects in East China.
