摘要
针对目前尚没有理想的基层材料抗冲刷实验仪器与实际冲刷很好关联的问题,首先介绍了半刚性基层材料的冲刷机理,并对冲刷试验仪器的发展历程进行了综述。通过对前三代抗冲刷仪器的特点分析总结了其各自的优缺点。在此基础上提出了考虑试件排水性能的抗冲刷试验的新思路,以更好的模拟基层产生冲刷破坏的实际服役环境。
In view of the problem that no ideal base material anti-scouring experimental instrument and the actual erosion was well related,this article first introduced the erosion mechanism of semi-rigid base materials,and summarized the development process of the erosion test instrument.Through the analysis of the characteristics of the first three generations of anti-scouring instruments,their respective advantages and disadvantages were summarized.On this basis,a new idea of anti-scouring test considering the drainage performance of the test piece was put forward to better simulate the actual service environment of erosion damage caused by the base layer.
