| Zusammenfassung: | The invention discloses an urban underwater overpass tunnel system, which comprises a mainline tunnel and ramp tunnels. The mainline tunnel downwards penetrates into a water system, two ends of the mainline tunnel are connected with ground connection roads, one end of each ramp tunnel is connected with the mainline tunnel while the other end of the ramp tunnel is connected with another surface road, and an underground flyover crossing relation is formed between the mainline tunnel and the ramp tunnels or among the ramp tunnels. The urban underwater overpass tunnel system is structurally characterized in that under the premise that new underwater corridors are not added and the position of the mainline tunnel is not changed, the ramp tunnels are added, one end of each ramp tunnel is connected with the mainline tunnel while the other end of the ramp tunnel is connected with the other surface road, so that an underground overpass is formed, the utilization rate of underwater corridors is increased to the greates |
