Abstract:Research purposes: The Yichang - Wanzhou Railway is in the very complex geological condition area where was called as the " forbidden zone" of railway construction,and there was a huge geological risk in tunnel construction.The main body of Major tunnel was buried deep inside mountain. The technical means of investigation only could detect the shallow statum,and it was difficult to detect deep stratum. So the contradiction between " Unable to fully detection and requiring full detection" always existed in tunnel construction. In order to solve this contradiction,what to do was to strengthen the geological survey work by conducting geological forecast for tunnel construction based on the previous geological survey.
Research conclusions: The " classification of geological complexity in tunnel construction " was researched and developed to realize the " geological prediction design for tunnel construction" and place it into the standard management range. This method could ensure the safe construction of tunnel and push forward the geological forecast work with obtaining good result.
