中文摘要:
      三维激光扫描技术主要应用于地形测绘、建筑物建模以及文物修复等,为了拓展这项技术在物理模型试验上的应用,利用Trimble CX型三维激光扫描仪对宽肩台抛石堤物理模型整体形态进行测量,并联合使用Trimble realworks 9和GMT 5.4两款软件对扫描数据进行处理并成图。与相机照片相比,三维激光扫描技术具有操作更便捷、精度更高、可视化效果更突出等特点,在物理模型上能够取代部分传统测量仪器的功能。试验前后扫描结果显示,宽肩台抛石堤在波浪作用下会发生明显变形,但最终会形成动态稳定的S形剖面形态。
英文摘要:
      3D laser scanning technology is mainly used in topographic mapping,building modeling and cultural relic restoration.To expand the application of this technology in physical model test,Trimble CX 3D laser scanner is used to measure the overall shape of physical model of riprap dike with broad shoulder,and then the scanning data are processed and mapped by Trimble Realworks 9 and GMT 5.4.Compared with camera photos,3D laser scanning technology possess the characteristics of more convenient operation,higher accuracy and more outstanding visualization,and it can replace some functions of traditional measuring instruments in physical model.The scanning results before and after the test show that the riprap dike with broad shoulder will deform obviously under the action of waves,but eventually changed into a dynamic stable S-shaped profile.
