| Concrete dams have been widely used in dam construction due to their convenient flood discharge and good seismic resistance in China.However,due to some factors such as aging,geology,and climate,the dam is prone to cracks and deformation problems.The crash has serious consequences.The operation and management capabilities of the company put forward higher requirements.Therefore,it is of great engineering significance to carry out relevant research on the safety management of concrete dams,to understand the operation status of the dam,and to discover the security problem of the dam timely.This paper studies the safety management of concrete dams from two aspects: deformation prediction and three-dimensional visualized intelligent management,establishes a threedimensional simulation scene of the study area,proposes a dam deformation prediction model based on deep neural networks,and develops a three-dimensional visualized intelligent management system for concrete dams.This realizes the visualization,information and intelligence of dam safety management.(1)Based on geographic information system(GIS)technology and three-dimensional visualization technology,research on 3D full-view simulation of concrete dams.Construct hydraulic building model and research area terrain model,compare and select 3D simulation scene fusion platform,solve the problem of difficult fusion of 3D model and digital terrain and easy loss of model material,and realize 3D full view of concrete dam simulation.(2)Aiming at the complexity of the mechanism between concrete dam deformation and deformation factors,combined with the advantages of deep learning network for mining complex feature information,design a combination of dam deformation based on Convolutional Neural Network(CNN)and Gated Recurrent Unit(GRU).The combined forecasting model of dam deformation is combined with engineering examples to verify the validity and feasibility of the proposed model;based on act.(3)According to the engineering requirements,put forward the system design objectives,design the technical framework,and determine the module functions of the R & D system.Based on Visual Studio platform,Arc Scene secondary development technology and 3D full view model of concrete dam,a 3D visualization module is established to realize the functions of concrete dam monitoring point information query,3D scene browsing and viewing,and realize the integrated application of database and 3D model;Based on database technology,the linkage mechanism of spatial database and attribute database is established,and the data monitoring module is established to realize the real-time viewing of deformation data of dam monitoring points;Based on the established prediction model and early warning indicators,a prediction and early warning module is established to realize the prediction and early warning of dam deformation data,and provide a platform support for three-dimensional visual intelligent management of concrete dam. |
