Application of BIM application benefit evaluation model based on fuzzy AHP in the whole life cycle of tunnel engineering

Tunnel engineering plays an important role in traffic planning, but it faces many problems in the process of periodic construction because of its large construction scale, long investment and construction time and prominent geological disaster risk. This paper introduces the life-cycle theory and establishes the benefit evaluation model of BIM Technology Application under the guidance of fuzzy AHP. The comprehensive operation rate of the model has been improved by 59.9% under both the construction level and the operation level of the project. And the weight score of some engineering indicators is also more than 90 points, which greatly improves the project management-level and coordination efficiency. This model can effectively provide new application ideas for engineering construction, and establish the benefit evaluation system of BIM application in the whole life cycle.
