摘　　要：堤防溃口模拟试验时,因模型较小且模型的堤防较软,易变形坍塌,致使常规测量技术难于捕捉到准确的堤防溃损信息。针对上述缺陷,引入非接触式数据获取方法,采用激光雷达仪对溃口模型进行扫描,然后进行点云数据处理。结果表明:激光雷达技术与传统的手工量测方法相比,具有速度快、精度高的优点,且避免了接触式量测的弊端,为模型试验的研究提供了新的方向。In the simulation experiment of dike break,it is difficult to obtain the accurate information of the dike break and its influence by using traditional measuring technology,because the dike model is small and soft,which is easy to deform or collapse.Therefore,the non-contact data acquirement method is presented,the model of the break is scanned through the laser radar technology,and the data are treated by scattered point cloud.The result shows that comparing with traditional manual measurement method,the laser radar technology has the advantages of quick speed and high precision and it can avoid the disadvantage of contact measurement,which provides a new research direction for model test.
