本文根据细沙多河流的原型河床边界条件; 通过物理概化模型试验; 较系统地研究了细沙河床桥墩附近水位变化、冲刷过程及冲刷坑形态等问题后; 发现当局部冲刷停止时; 床沙中径相应变粗1.5——2.5倍; 而且实验曲线进一步反映了桥墩冲深随行进流速增加而加大的变化趋势。此外文中还对多沙细沙河流工程附近的局部河床冲刷的试验模拟充法进行了深入探讨; 并对有关计算公式进行了检验与分析。

Based on the prototype of the samada rivers in the river bed, this article, through the physical predictive model test, systematically studied the problems of water level near the pier near the slim pier of the sloppy, and the formation of the pits. When it was found that the local scouring was stopped, the corresponding diameter of the bed and sand became thicker 1.5 to 2.5 times, and the experimental curve further reflected the increase in the increase of the pier depth of the pier. Trends. In addition, the test simulation method of the local riverbed washed by the Disa Nishisha River project in the text also discussed and analyzed the relevant computing formula.
