Either high or low embankment,design of erosive protection for freewayss always the same There is no protection design where it needs to be protected;whereas there are plenty of protections where it needs not to be protected So,by means of testing observation and investigating,the influence of the slope length on erosion of freeways' slope and their relation are analyzed under the rainfall condition in Jiangsu area,based on actual freeway projects in Jiangsu province The critical height of protection for freeway embankment is acquired by which different types of protection are measured off to fit different embankment height,with useful data and recommendations for freeway protection design.

目前高速公路边坡冲刷防护设计往往千篇一律 ,不论路堤高与低 ,一个统一模式 ,需要防护的地方未能很好地防护 ,而部分不需防护的地方都大量设计了防护工程。为此 ,本文结合江苏省高速公路建设的工程实际 ,采用试验观测与调研二者相结合的方法 ,分析了江苏地区降雨条件下 ,高速公路边坡坡长对坡面冲刷的影响及二者之间的关系 ,初步得出了江苏省高速公路路堤边坡冲刷防护的临界高度 ,这样可以划分不同防护类型适应的路堤高度。文中一些有益的数据和结论 ,可供今后高速公路边坡防护设计参考。

Based on necessity of erosive protection for embankment slope and deficiency of research on erosion calculation model of slope, the hydraulics particularity of embankment slope is analyzed and the processes of water-erosion of slope are described on energy by the conservation and transform principle of master energy. According to the energy balance equation, the water-erosion model of slope is put forward to calculate erosive quantity. In order to verify the model, the SR style artificial rainfall simulator is rebuilt to conduct a series of experiments at high embankment segment of Shihuang freeway. The comparison analysis between the data collected in field and calculated by the model shows an ideal forecast effect of the model.

基于路堤边坡冲刷防护的必要性及目前冲刷量计算模型研究存在的不足,在分析边坡径流水力学特性的基础上,根据物质能量守恒和转化原理,对边坡土水力冲刷过程从能量的角度进行描述,按能量平衡方程导出土水力冲刷的冲刷量计算模型。为了验证该模型,在石黄高速公路高填方边坡用改造的SR型人工降雨设施进行冲刷试验,得到冲刷量实测资料,用模型计算的冲刷量值与之比较,显示了模型具有较好的预测效果。
