| Abstract: | Single- trumpet interchanges in mountainous area shall be designed in accordance with the line development of the topography. After the calculation of cut ＆ fill earthwork by measuring the line, the line has been adjusted and optimized constantly, which makes the cut ＆fill earthwork not only satisfy the line indicators but also the most affordable. The dispersion between the principle line and the road which it cuts across has been considered comprehensively, the ramp longitudinal slope has been laid out properly. The fill height of the toll plaza has beeri measures shall be taken. |
