摘要
针对目前对砂性土边坡冲刷破坏研究的不足,对基于能量法的路堤边坡冲刷量公式进行了修改,使其可应用于砂性土路堑边坡冲刷量计算,结合室内边坡冲刷模型试验,对计算公式的合理性进行了验证,并根据试验现象得到坡面冲刷破坏的一般规律.研究结果表明,修改后的冲刷量公式在计算砂性土边坡冲刷量时具有较好的准确性.
As the current research on the erosion failure of sandy slope contains deficiency,this paper modifies the energy based calculation formula for embankment slope erosion to enable it to calculate the erosion quantity of sandy cutting slope.By conducting laboratory model test of slop erosion,the modified formula is verified and the general laws of slope erosion are obtained.The study shows that the modified formula has good accuracy in the calculation of the erosion quantity of sandy slope.
