摘　　要：基于目前涉水岸坡失稳机制研究中模型试验这一具体工具和方法,通过文献调查及装置设计改进,讨论了当前涉水岸坡失稳机制研究中渗流潜蚀流失颗粒相关物理模型试验研究方法及装置的发展方向.通过对不同渗流潜蚀模型试验装置及方法分析,特别是其流失颗粒量化评价模式的改进,提出了渗流潜蚀颗粒流失量化分析相关的四代模型装置划分意见并指明了各代之间的关联与区别.探讨了相关模型试验的第四代新装置案例:一种模拟水位变动下土坝或堤岸渗透破坏的模型试验装置及其新思路,通过案例分析探讨了渗流潜蚀相关模型试验的发展与变革.Based on the model test,which is a specific tool and method in the current study on the instability mechanism of water-related bank slope,this paper discusses the development direction of the physical model test method and device for the study on the instability mechanism of water-related bank slope through literature investigation and device design improvement.Based on the analysis of different seepage erosion model test devices and methods,especially the improvement of their quantitative evaluation model of particle loss,the division of four generations of model devices related to the quantitative analysis of seepage erosion particle loss is proposed,and the correlation and difference between each generation are pointed out.The main changes in the construction method and test research of model test devices in current relevant research are analyzed.A new model test device of the fourth generation is discussed,which is apt for simulating the seepage failure of earth dam or embankment under the change of water level and its new idea.
