北翟路地下通道全长1760m,呈东西走向,西起外环线地面交叉口西侧,东至与现状中环线立交主线落地段接顺处,暗埋段全长1480m,敞开段长280m,布置为双向6车道。传统长大隧道多为公路或越江隧道,缺乏自然通风排烟建设条件,采用纵向机械通风、排烟方式,地下空间占用大、前期土建工程费用高、集中排放的风塔选址也非常困难,后期运维成本激增。北翟路工程地面道路设置中央分隔带,地道主线在分
Beidi Road underground passage length of 1760m, showing the east-west direction, west of the outer ring road junction west, east and the current Central Link Interchange main line landing along the segment, the total length of buried section 1480m, open 280m long, layout For two-way 6 lanes. Most of the traditional long tunnels are highways or cross-river tunnels. There is a lack of natural ventilation and smoke exhaust construction conditions. Longitudinal mechanical ventilation and exhaust methods are adopted. Large underground space is occupied. In the early stage, the cost of civil engineering works is high. It is also very difficult to locate concentrated wind towers. Post operation and maintenance costs surge.
