铁路大提速下的弯道设计

In the face of growing production and living needs of the national economy as the main artery of the urgent need to high speed railway. In this paper, combined with knowledge of physics, applied calculus and analytic geometry approach, Study on the radius of curve , the angle of curve and ultra-high, the role of buffer zone in the train moving and account of the number of relationships between them detailly ,Combined with the actual situation of our country which the passenger and goods is in the same rail.focused on the railway under the speed of traffic safety and the possibility of re-acceleration and other and give the problem to analyze and solve.
