Precipitation, bias angle, excavation width, flat rate, excavation method, the rock level, bad geology, groundwater, weathering degree, overbreak degree, working face is closed, the level of construction technology, the 13 elements of management technical level as two indicators. Through the combination of evaluation standard and the two indicators. To build a more reasonable tunnel construction risk evaluation index system of.3. extension theory and AHP to determine the combination of classical domain and joint domain index, and establishes the matter-element matrix and correlation calculation method of tunnel construction risk. On this basis, put forward the risk assessment of tunnel construction levels the extension model and the analysis method of.4. using the theory method of the establishment of the Ge Jia Gou tunnel of actual risk assessment. According to the field monitoring measurement and information feedback, prove the tunnel level extension model based on A risk assessment method is reliable, the risk model provides a theoretical basis for.5. using hierarchical extension model to evaluate the risk of stone ditch tunnel project as an example of tunnel construction risk evaluation, results show that the level of extension model price evaluation method in the large section tunnel risk is reliable.
