利用Unity3d、WebGL技术、OpenGL技术、3D仿真技术,开发了基于桥梁工程病害阈值控制指标识别的《桥梁技术状况评定虚拟仿真实验》项目。应用《桥梁技术状况评定虚拟仿真实验》教学系统,构建覆盖实验“预习、实施、复习、考核”全过程的“虚实结合”实施流程,既可较好解决单一实体实验由于“成本”、“安全风险”和“进度安排”的限制而致“病害检测操作复习难、考核难,公路桥梁组成构件空间分布位置再现难,技术状况评定示教效果差”等问题,还可增强学生在进入实体工程现场前对分部件在工程空间位置关系的感性认识、桥梁工程检测与技术状况评价的“规范化”操作流程,实现《桥梁技术状况评定虚拟仿真实验》实验项目“完整、高效、绿色、环保”开出和考核对实验过程的全覆盖。

Using Unity3D, WebGL technology, OpenGL technology and 3D simulation technology, the project "Virtual Simulation Experiment of Bridge Technical Condition Assessment" was developed based on the identification of bridge engineering disease threshold control index. The application of the technology of bridge condition assessment of virtual simulation experiment teaching system, build cover experiment "preparation, implementation, review, examine the whole process of the" mix "of the implementation process, can better solve the single entity experiment because of" cost ", "security risk" and the limitation of "schedule" to "disease detection operations review, assessment, highway bridge members spatial location representation, technical condition evaluation of teaching effect is poor", Also can strengthen the student before entering the entity project site on the division of spatial position relationship between perceptual knowledge of the project, the condition of bridge engineering detection and evaluation of "normalization" operation process, realize the bridge technique condition evaluation of virtual simulation experiment "integrity, high efficiency, green, environmental protection" open and examination of full coverage of the experimental process.
