特长隧道综合超前地质预报应用研究

Application of Comprehensive Advanced Geological Prediction Method in Extra-long Tunnel

根据白鸽岭特长隧道的地勘察资料,结合隧址区现场踏勘的成果采用地质分析法对隧道整体地质情况进行预报,并在此预报结果基础上,采用先进的TGP法对隧道进行长距离预报和瞬变电磁仪法对隧道进行短距离地质预报,物探方法和地质方法的结合较好弥补了现有物探方法的不足。

The whole geological of tunnel was forecasted using geological analysis method based on survey data of extra-long Baigeling tunnel and site investigation results of tunnel. The tunnel geology advanced prediction method and transient elec- tromagnetic method were also applied to predict long distance and short distance tunnel geology, separately. The predicted results show that the combination of geophysical exploration method and geology method can make up the deficiency of the existing geophysical exploration method.
