Stuy On Creating For 3D Model And Model Information Application Of Sidong Reservoir

The establishment of 3D model is the basis of BIM technology,and the application of model information is the core of BIM technology.At present,many scholars are devoted to the application of model information.So,based on the preliminary design of Sidong reservoir in Jiangxi Province,we used AutoRevit software to simulation the 3D model of earth-rock dam,spillway and diversion tunnels.As a whole,we had made three aspects of the research.(1)Based on engineering drawings generated by the section and the view tool,we established the relationship between 3D models and 2D drawings.(2)Besides,in order to building the relationship between 3D model and budget,we compiled the plug-in by c# language to count engineering quantities of 3D model and combined Excel of budget to generate the bill of quantities and budget automatically.(3)Combining the construction schedule with the program based on VB,we could count artificial,materials and machinery resources planning automatically in each period,combined the planning with 3D model.?A slight move in one part may affect the situation as a whole? is the most typical characteristics of AutoRevit technology,so that a modification of the model could cause the change of engineering drawings,the budget and the artificial,materials and machinery resources plans.The main research contents and conclusions are as follows:(1)Referenced to the method for modeling with Revit in construction field,we completed the creation of Sidong reservoir earth-rock dam,spillway and diversion tunnels by the way of creating ?loadable family?.Then,parameterizing all the family to complete information integration of the project,this enriched water conservancy project family.(2)Providing 3D visualization management of earth-rock dam,spillway and diversion tunnels project,we marked on three views and sectional view to create drawing,which propitious to the precise construction for construction side.Forming linkage between the formations of drawings,any changes of drawing could transfer to others in round-trip,maintaining the consistency of all drawings.(3)Using the AutoRevit plug-in by c# language,we extracted attribute and geometry information of model artifacts for the statistics of project quantity,and then passed to excel Table.We built the bill of quantities by categorizing the project and calculated project unit price and various fees to generate the total project investment based on quota.In the process,bill of quantities and the project division could be generated automatically.At the same time,the relationship between 3D model and table established,so the change of model could be passed to the table,keeping the consistency between the model and the budget table.(4)After linking the bill of quantities and corresponding unit price in division component project,we need to link work-schedule and unit price for the project in a way.Based on the program by VB and the construction schedule of each division component project,we used the engineering quantities to count up the consumption of the artificial,materials and machinery resources in each period,which is a resource planning in the construction organization.Due to budget excel table has established dynamic associated with 3D model,the construction organization plan based on the 3D model had established in fact.
