| Long distance water diversion project is not only able to alleviate and solve the serious problems of water and soil resources in China at present,but also bring about the comprehensive benefits of water power,flood control,shipping and aquaculture;But the traditional project management mode has not been able to meet the water diversion project construction process with the attributes of long line span,large investment,many participants and long construction period.In this paper,the information integration theory of lifecycle management is applied to the construction process of long distance water diversion project.Based on the GIS and BIM technology which realize lifecycle management,the combination of GIS model and BIM model are studied and implemented.Finally,the GIS-BIM system used in the lifecyle management of long distance water diversion project is developed by using the above theory,this system can run through the whole professional fields,and provide effective decision support for the construction of water diversion project.The works of the study are as follows:(1)Firstly,this paper introduces the lifecycle management and information integration theory,and the basic content of BLM(Building Lifecycle Management)is discussed based this theory;Secondly,focusing on the BIM(Building Information Model)which is regarded as core technology of realizing BLM;Lastly,these are applied to the information management in the construction process of long distance water diversion project,in order to solve the problem of serious loss of information,low efficiency of engineering design,and lack of information sharing level.(2)Geographic Information System-GIS emphasizes on the application of data acquisition,storage,processing,transmission and so on,it has a very strong spatial analysis capability;3DGIS scene which is based on simulating the real space environment is constructed by 3D terrain surface model and building 3D model,and it can display and spatial analysis of geographic information.(3)GIS focuses on the integration and management of external environment information and BIM emphasis on all stages of information in the project itself,these promote the application of the integration of the two technology;In this paper,the integration method mechanism of GIS with BIM is discussed from the storage standards of both data models,integration modes and integration methods.(4)The BIM applications can be integrated into 3DGIS platform based on the Geographic Information System-Skyline,the GIS-BIM system used in the lifecyle management of long distance water diversion project is developed under the network environment,and used in practical engineering. |
