Experience of the highway alignment design

This paper introduces the line settlement,the curve settlement,and the broken back curve disposition,summarizes some keys about highway alignment design,the practice shows that the plane and vertical line type design combined with the terrain in the hilly area not only can achieve the good visual effect,but also can make the road and the environment coordination and reduce the engineering quantity of the soil excavating and the earth fill.
