The tunnel is located at the 3th section of the highway of Yichun to Hegang . It is a linear separated one-way tunnel with two lanes on eachside . The uplink is K20+163～K21+587 , and its total length is 1424m . The downlink mileage is K20+155～K21+600 , and its total length is 1445m .The strength of the surrounding rock of the tunnel belongs to III and IV level. This tunnel is designed as double slope, and the slope is 1% . The combined type is used linking . The cross section form of the tunnel is curved wall’s aches, and the tunnel portal is designed as the wing wall. Meanwhile, the open cut hole and the dark hole have the same form . The open excavation method is used to construct the open cut hole, and the dark hole was constructed by NATM . The main content of this design includes the overall tunnel design, the open cut hole design , the lining design , ventilation and lighting design , waterproof and drainage design, construction scheme design . According to the overall tunnel design determined the tunnel plane , vertical section and cross section
