Tunnel structure capable of improving ship trafficability
The invention discloses a tunnel structure capable of improving the passing capacity of a ship, which comprises an upstream tunnel and a downstream tunnel, and a communicating hole positioned at the bottom of the upstream tunnel and the downstream tunnel is arranged between the upstream tunnel and the downstream tunnel; the optimal distance range of the two adjacent communicating holes is +/-10% of the design representative ship type length; the top elevation of the communicating hole is not higher than the ship draft. The method has the advantages that (1) the cross-sectional area of the communicating hole is very small, the construction is simple, and the increased cost is very small compared with the expansion of the cross-sectional area of the navigable tunnel; (2) the transverse flow generated by the communication hole cannot influence the safe navigation of the ship; (3) the sailing resistance of ships in the tunnel can be effectively reduced, the fuel oil of the ships is saved, and good energy-saving and emission-reducing effects are achieved; and 4, the maximum safe navigational speed of the ship passing through the tunnel can be increased, and the tunnel passing capacity is improved. In conclusion, on the premise that the sectional area of the navigable tunnel is not enlarged, the sailing resistance of the ship in the tunnel can be effectively reduced, the shore-to-shore navigational speed of the ship in the navigable tunnel is increased, the tunnel trafficability is improved, and the application prospect is wide.
本发明公开了一种可增加船舶通过能力的隧洞结构，包括上行隧洞和下行隧洞，在上行隧洞和下行隧洞之间设有位于其底部的连通洞；相邻两个连通洞的最佳间距范围为设计代表船型长度±10％；连通洞的洞顶高程不高于船舶吃水深度。本发明的优势在于，①连通洞断面面积很小，施工简单，相对于扩大通航隧洞断面面积，增加的成本很小；②连通洞产生的横流不会影响船舶安全航行；③可有效减小隧洞内船舶航行阻力，节省船舶燃油，起到很好的节能减排作用；④可增加船舶通过隧洞的最大安全航速，提高隧洞通过能力。综上，本发明在不扩大通航隧洞断面面积前提下，可有效减小隧洞内船舶航行阻力，增加通航隧洞内船舶对岸航速，提高隧洞通过能力，应用前景广泛。
