摘　　要：为直观准确地理解和分析疏浚工程水下土质空间分布情况,提出疏浚工程土质建模与可视化分析方法。基于数据库技术、土质三维建模技术、模型检测与集成技术,建立疏浚土质集成模型。采用程序开发平台Visual Studio 2005,基于OpenGL和OpenNURBS,研制疏浚工程土质三维建模与可视化分析系统,实现了数字钻孔勘探模拟、三维任意剖切分析、土质信息实时查询、疏浚工程量计算分析以及其他成果输出等功能。实例应用表明,该系统不仅具有界面可视化、操作性强、自动化程度高、运算速度快等特点,而且其疏浚工程量计算方法提高了计算精度,计算时间缩短约50%,大大减少了土质分析工作量,能够更好地满足疏浚工程的实际要求。In order to understand and analyze the spatial distribution of underwater soil texture in dredging engineering,a method for soil texture modeling and visual analysis is put forward.Based on database technology,three-dimensional soil modeling,model testing,and integration technologies,a three-dimensional soil texture integrated model was built.A modeling and visual analysis system for soil texture in dredging engineering was developed using the platform Visual Studio 2005,based on OpenGL and OpenNURBS.Functions such as digital drilling,three-dimensional arbitrary cutting,real-time query of soil information,and dredging volume calculation were realized.Application results show that the system has the advantages of a visual interface,strong operability,high automation,and fast operation.Moreover,the proposed method for dredging volume calculation has higher precision and the calculation time can be reduced by about 50%.The system can greatly reduce workload in soil analysis and satisfy practical requirements of dredging engineering.
