BIM+GIS地下洞室施工期智慧建造与数模联动方法OA

Aiming at the problems of low management efficiency and data island caused by complex geological conditions,tightly coupled working procedures and frequent design changes during the construction of underground cavern engineering,this paper constructs a three-dimensiona l visual intelligent construction implementation framework based on BIM+GIS.Firstly,the refined BIM model,3D geological model and GIS real-scene environment for the construction period are established.Secondly,under a unified coding system,a dynamic automatic association method between component-level models and Work Breakdown Structure(WBS)is proposed,which supports the deep integration of business data involving schedule,quality and safety with the models.Finally,a three-terminal collaborative management system covering Web terminal,mobile terminal and large screen terminal is developed to realize digital-model linkage and closed-loop management and control.Engineering application results show that the time consumed for single component information query is reduced from 15 min to 5 min,the closed-loop dispatch time of quality problems is shortened from 2 h to 0.5 h,the material over-consumption rate in unfavorable geological cavern sections drops from 5％to 2％,and the comprehensive cost is reduced by about 8％.The proposed method can provide a replicable technical route for the intelligent construction of similar underground cavern projects during the construction period.
