| The water diversion project is easily affected by natural factors,human factors and social factors.It may cause engineering damage such as structural damage of buildings and instability of channel slopes.The formation of engineering hazards often develops in the form of cracks.Through the virtual simulation technology,the engineering danger situation is simulated,and the emergency plan is visually displayed.It aims to provide a new technical support for the safe operation and emergency rescue of the water diversion project.This article takes this as a starting point and studies the following:1.Taking the concrete fracture process as the research object,based on the linear elastic fracture mechanics theory,the cracking and displacement state of the concrete structure is calculated by the meshless radial base point interpolation method.2.The virtual simulation method of cracking process of concrete structure is studied.The geometrical modeling of the simulated object is carried out.The noise surface method is used to reconstruct the fracture surface morphology of the concrete structure,and the concrete cracking process is realized by computer animation technology.In the Unity3 D engine,the virtual scene of the water diversion project is built.Combining the texture texture and the light rendering technology,the 3D model in the scene is rendered,and the virtual reality technology is used to express the concrete cracking danger in the water diversion project.3.According to the danger of concrete cracking,an emergency rescue plan based on augmented reality technology is proposed.Establish a three-dimensional model for emergency equipment and emergency materials.The mobile device terminal is used as a platform to perform three-dimensional registration on the camera of the device.The user can view the threedimensional virtual model with the mobile device terminal,understand the rescue plan and drawing information,and realize the comprehensive display of the emergency rescue plan. |
