摘　　要：为了探讨公路边坡冲刷深度的主要影响因素,通过建立模拟路基模型,进行模拟路基试验,研究了压实度、冲刷时间、水流速度等因素对不同位置边坡冲刷深度的影响规律。试验结果表明:边坡最大冲刷深度随着压实度的增大而降低、随着冲刷时间和水流速度的增大而增大,冲刷深度与压实度和水流速度之间分别具有线性相关和指数相关关系,增大压实度可以有效提高边坡的抗冲刷能力。In order to investigate the main factors influencing the scouring depth of highway slope,a simulated subgrade model is established.Through the simulated subgrade test,the influencing factors of compaction,scouring time and water velocity on the scouring depth of slope at different locations are studied.The test results show that the maximum scouring depth of highway slope decreases with the increase of compaction and increases with the increase of scouring time and water flow velocity.There are linear correlation and exponential correlation between scouring depth,compaction degree and flow velocity.The highway slope anti scouring ability could be effectively improved with the compaction increasing.
