沿河路基局部冲刷深度的试验与分析

The examinational study on the local scour depth of roadbed along river

文章讨论了公路沿河路基局部冲刷机理及影响冲刷深度的主要因素,通过模型试验,利用实测数据、量纲原理及回归分析得出适用于新疆315国道芒崖-且末段的路基局部冲刷深度计算公式,为公路水毁的改造提供了理论依据和技术支撑.

In the paper,scour mechanism and factors influencing the scour depth of roadbed along river are analyzed.Through the method of theoretical analysis and experiment study,the formula of the maximum scour depth of prevention wall in concave bank of G315 is put forward.The formulation of the maximum scour depth is theoretics and technic bases of protecting water scour.
