【摘要】：深圳至中山跨江通道工程(简称深中通道)连接深圳和中山两市,跨越珠江口内伶仃洋"三滩两槽",大型人工岛及大量桥墩的存在必然对珠江口水域的水流动力环境造成一定的影响。通过伶仃洋潮流物理模型试验,研究深中通道各工程方案对珠江口水动力环境的影响。研究结果表明:A2方案(伶仃航道隧道+矾石航道桥梁)对潮位影响最大、其他次之;人工岛及桥墩附近水域流态变化较明显,以人工岛最大,通风井、锚碇、主塔、索塔等建筑物次之,非通航桥墩附近流态变化不明显,桥轴线5 km以远水域已基本不受工程影响。总体而言,各工程方案对伶仃洋滩槽格局影响都不大,结合其他专题研究,一致推荐A3方案(伶仃航道桥梁+矾石航道隧道)作为深中通道合理可行方案。
[Abstract]:The Shenzhen to Zhongshan River Crossing Project (referred to as Shenzhen Central Passage) connects Shenzhen and Zhongshan cities. The existence of large artificial islands and a large number of piers across the Lingdingyang "three beaches and two channels" in the Pearl River Estuary will inevitably have a certain impact on the hydrodynamic environment in the Pearl River Estuary. Through the Lingdingyang tidal current physical model test, The effects of various projects on hydrodynamic environment in the Pearl River Estuary are studied. The results show that the influence of the two schemes (Lingding Channel Tunnel Bauxite Waterway Bridge) on the tidal level is the greatest, followed by the others. The change of flow pattern in the water near artificial island and bridge pier is obvious, in which artificial island is the largest, ventilation well, Anchorage, main tower, cable tower and other buildings take the second place, and the flow pattern in the vicinity of non-navigable bridge pier is not obvious. The distant waters of the bridge axis of 5 km have been basically unaffected by the project. In general, all the project schemes have little effect on the Lingdingyang trough pattern, and combined with other special studies, A 3 scheme (Lingding waterway bridge bauxite channel tunnel) is recommended as a reasonable and feasible scheme for deep middle channel.
