Floating forest: A novel breakwater-windbreak structure against wind and wave hazards

《结构与土木工程前沿（英文）》 2021年第15卷第5期页码 1111-1127 doi: 10.1007/s11709-021-0757-1

摘要： A novel floating breakwater-windbreak structure (floating forest) has been designed for the protection of vulnerable coastal areas from extreme wind and wave loadings during storm conditions. The modular arch-shaped concrete structure is positioned perpendicularly to the direction of the prevailing wave and wind. The structure below the water surface acts as a porous breakwater with wave scattering capability. An array of tubular columns on the sloping deck of the breakwater act as an artificial forest-type windbreak. A feasibility study involving hydrodynamic and aerodynamic analyses has been performed, focusing on its capability in reducing wave heights and wind speeds in the lee side. The study shows that the proposed 1 km long floating forest is able to shelter a lee area that stretches up to 600 m, with 40%–60% wave energy reduction and 10%–80% peak wind speed reduction.

以旋涡塔阵建立速成及高效益的人工防护林带化整片沙漠为大片绿地

摘要：

改造沙漠、利用沙漠，必须在沙漠中建立多道防护林带，才可大力推展沙产业、改良沙漠环境、并逐步化整片沙漠为大片绿地。对此，目前世界各国均束手无策或认为不可能。文章建议以旋涡塔阵及流体力学中的旋涡破裂特性及与镇定仓等的相互干扰，将塔阵后方的强风变为湍流弱风，而建立速成及高效益的人工防护林带；适当的重量分布在各镇定仓内，可使旋涡塔阵在狂风中仍屹立不移，在弱风区中，可大力推展沙产业，并与多方面的专家合力，适度开发利用沙漠；化整片沙漠为大片绿地，化荒芜及有严重危害的沙漠为宝地，并可在沙漠中以旋涡塔阵，保护长期及深层探勘的工作区，以利于发现及测定深埋地下的世界级的矿藏。
