| 3D-design will bring about tremendous technical progress for the hydropower project,and it will also push the design mode onto an unprecedented level. The 3D-designidea based on CAD / CAE integrated analysis concept realizes the full data sharingand unification between design process and check process. 3D-design research ofhydropower project has been carried out step by step currently, and the 3D geologicalresearch also has been developed a lot, but most were not related to the CAD / CAEintegration analysis theory. Taking the Gravity Dam 3D-Design Platform as workfoundation, the entity geological modeling module based on CAD / CAE integratedanalysis and Smart excavation design module based on the entity geological modelwas studied and developed based on previous achievement in this paper.(1) The significance and necessity of building entity geological model in CAD /CAE integrated 3D design platform of hydropower project was explored. TakingAutodesk company's products CIVIL3D as working platform, VB was used asdeveloped language for the development of entity geological modeling module underthe "Gravity Dam 3D-design Platform ". The information and models sharing betweenthe CAD and CAE software was realized through the intermediate processingplatform and geological information database.(2)A 3D-design method of excavation was found, and the intelligent excavationdesign module based on the entity geological module was developed which allowedusers to design in a 3D environment and determine excavation program, real-timetransforming the excavation programs into 3D excavation model and the quickstatistic of quantities was realized, and then the optimization between multiplyexcavation programs was taken.It was a very good attempt to apply the system developed in this paper whichbased on CAD / CAE integrated three-dimensional design technology intohydropower engineering project, and it indicated that there was high practical value. |
