Abstract
BIM technology has already got relatively extensive application in the field of domestic architecture, but it is rarely used in the tunnel engineering construction. To solve the problems such as the construction of car cross channel and tunnel subject structure, the construction process control of the whole tunnel project build, the optimization of special construction scheme and the accurate and rapid calculation of quantities, Hangzhou Zizhi tunnel engineering adopts BIM construction application system completed by engineering three-dimensional digitalization technology, and the creation of subject tunnel model including geologic model is completed, five major categories of application points are realized. Combined with three-dimensional geological tool GeoStation and three-dimensional reinforcement software ReStation, specific tunnel construction solution based on BIM application is formed, the innovation and effect in the construction process of Zizhi tunnel is realized, the application value and broad development prospects of BIM technology in the tunnel construction is embodied.
