Abstract：Research purposes: Ground geological survey of Xiang － Pu Railway long tunnels face the problems of terrain level difference large，geological structure complexity，vegetation thick，bedrock outcrops lack，surveying cycle short，large area geological surveying and mapping difficulty，and it is difficult to quickly and accurately for large scale region engineering geological information．
Research conclusions: Based on the study of muti － geological information integration，3D visualization remote sensing image modeling and 3D visualization remote sensing image interpretation method to establish route，physiognomy and geology 3D scene of DaiYun － shan to Gao Gai － shan Zone for qualitative interpretation of the morphological characteristics，fault structures and bad geology． Interpretation results can effectively guide geological survey，reduce the workload，ensure tunnel large scale geological survey precision．
