【摘要】：建立東海-黃海-渤海大范圍風(fēng)暴潮二維數(shù)學(xué)模型,對9216臺風(fēng)風(fēng)暴潮過程進(jìn)行模擬,分析渤海灣造陸工程前后風(fēng)暴潮增水對海河流域主要河口(海河口、永定新河口和獨(dú)流減河口)閘下區(qū)域最高潮位的影響,并探討有效降低河口閘下通道內(nèi)風(fēng)暴潮潮位的開發(fā)方式。研究表明:渤海灣圍填海工程實(shí)施后,閘下通道內(nèi)維持自然地形時,通道內(nèi)最高潮位高于工程前;閘下通道實(shí)施地形開挖后,通道內(nèi)最高潮位依然高于工程前,但較自然地形條件下抬高幅值有所減小。閘下通道結(jié)合開發(fā)建設(shè)港池航道等工程實(shí)施地形開挖,使得通道內(nèi)水深增加,可降低通道內(nèi)風(fēng)暴潮增水幅度。
[Abstract]:A two-dimensional mathematical model of storm surge in the East China Sea, Huang Hai and Bohai Sea was established. The storm surge process of typhoon 9216 was simulated, and the increase of storm surge water to the main estuary (Haihe estuary) in the Haihe River basin before and after the land building project in Bohai Bay was analyzed. The influence of the maximum tide level in the sub-sluice area of the Yongding New Estuary and the Monofluence Estuary) is discussed, and the development mode of effectively reducing the storm tide level in the channel under the estuarine sluice is discussed. The results show that the maximum tidal level in the channel is higher than that before the project when the natural topography is maintained in the subsluice channel after the implementation of the reclamation project in Bohai Bay, and the highest tide level in the tunnel is still higher than that before the construction after the topographic excavation of the subsluice tunnel. However, the elevation amplitude is smaller than that under natural terrain. In combination with the development of the port pool channel and other projects topographic excavation can increase the depth of water in the tunnel and reduce the increase of storm surge in the channel.
