受自然条件限制 ,许多丘陵及重丘区的公路都是沿河而建 ,其弊端是路基易遭水毁破坏。沿河而建的公路路基防护应根据不同方位的水流特性及冲刷特点来确定和计算构筑物的结构和防护方式。
Due to natural conditions, many highways in the hills and heavy hilly areas are built along the river. The drawback is that the embankment is easily damaged by water damage. Road embankment protection built along the river should be based on different directions of the flow characteristics and erosion characteristics to determine and calculate the structure of the structure and protection methods.
