以TGP超前地质预报理论和实际工程资料为基础，运用信息化逻辑方法对TGP二维与三维地质预报成果进行分析对比，主要从预报地质构造的位置、规模、围岩级别和产状四个成果比较二者的相同和不同之处。结果表明，对于隧道前方岩性无明显差异的围岩，二维与三维的地质预报结果基本相同；对于与隧道斜交的地质构造，二维与三维地质预报在构造产状预报结果上相近，但二维地质预报在围岩级别预测方面有利，三维地质预报在规模和位置的预报方面有利；对于与隧道激发炮孔连线一侧边墙不相交的地质构造，二维与三维地质预报结果基本不同，且三维比二维的地质预报结果有利。

Based on advanced theory of TGP ( Tunnel Geological Prediction) and actual engineering data, the authors applied informa?tion logic method to analyzing TGP 2D and 3D geological prediction results and mainly compared the similarities and differences in the aspects of the geological structure position, scale, surrounding rock classification and attutude. The results show that, if the surrounding rocks in front of the tunnel have no obvious difference in lithology, 2D and 3D geological prediction results are essentially the same. When the geological structures and tunnel are obliquely crossed, 2D and 3D are similar in the prediction results of tectonic attitude;however, 2D is advantageous in the surrounding rock classification prediction, and 3D is advantageous in the size and location predic?tion. Where the geological structure does not intersect with the tunnel side wall which is near the hole line excitation, 2D and 3D geo?logical prediction results are substantially different, and 3D geological prediction results are better than 2D prediction results.
