伶仃洋大桥总体布置河工模型试验研究

Hydraulic Modelling of the General Layout of Lingdingyang Bridge

为加速发展珠江两岸经济，发挥粤港澳的金三角作用，有关部门拟建一座长29公里的伶仃洋跨海大桥。本文所提供的成果，是在3种水文组合条件下，对两个大桥轴线布置方案，通过河工模型反复试验，选出对该水域有关水道的泄洪、纳潮、潮排、潮灌以及冲淤变化影响较小的大桥总体布置方案，为建桥提供重要的依据。

To accelerate the economic development around Pearl River Estuary and bring into full play the golden triangle of Guangzhou-Hong Kong-Macao, a 29 km long Lingdingyang Bridge is planned to be built by relevant departments. Hydraulic model tests have been made on two schemes of the layout of the bridge axis under the combination of 3 kinds of hydrologic conditions to select a general layout of the bridge which has less influences on the channels in this water area in flood disposal, flood entry, tidaldrainage and irrigation and the change of scouring and silting. The results will present in important basis for the construction of thebridge.
