KCAP + FELIXX 赢得深圳东部海堤重建竞赛，提出“三重海岸防线战略”

KCAP + FELIXX赢得深圳东部海堤重建的国际竞赛。这条长达130公里的岸线沿着位于香港和深圳之间海湾的天然绿色半岛——大鹏延展。2018年9月，台风山竹不同程度地破坏了半岛的基础设施。借此契机大鹏启动了重塑海岸安全的国际竞赛，提出高标准保护，预防频发极端天气事件的负面影响。KCAP + FELIXX联合体提出“三重海岸防线战略”。这是一个多层次、多功能的海堤防护系统，从全局层面实现应对多变海岸气候的适应性重组。水安全战略与全岛生态保育发展紧密相连，同时为社会和经济增长创造了弹性框架。6个场地覆盖32公里长的海岸区。目前KCAP + FELIXX从竞赛概念进入实施设计阶段，预计建设和实施将于2021年完成。

KCAP + FELIXX have won the international competition for the redevelopment of the 130-kilometer coastline of Dapeng, a green peninsula in the bay between Hong Kong and Shenzhen. In September 2018, the typhoon Mangkhut damaged the infrastructure of the peninsula to various degrees. An international competition was launched to develop a plan to restore the coastline and raise protection standards against the more frequent occurrence of extreme weather events. KCAP+FELIXX developed the ‘Triple dike strategy’, a multifaceted dike system that allows for an integrated approach towards the climate adaptive reorganization of the shore. Water safety strategies are connected to eco-development and nature restoration. This creates a resilient framework for social and economic growth. For 32 kilometers of coastline, KCAP + FELIXX is developing this concept into 6 strategic implementation projects. Realization starts this year, and is expected to be completed in 2021.

三重海岸防线 | TRIPLE DIKE

三重海岸防线与常规的海岸防洪墙不同。我们旨在以三重提防系统为框架，尊重场地现状，谦逊介入，并回应每个区域的特定未来需求。第一重“外堤”通过衰减波浪、减少海蚀和增强沉积来构建富有增长弹性的外部生态防护系统。第二重“中堤”是加高的堤坝，以阻止风暴潮以及高浪。我们并没有简单的把第二重提防视为一堵单一的防洪墙，而是将它设计成了一个多功能区：一个令人兴奋的丘陵公园、一个带有城市长廊的高架海滨、一个潮汐公园、甚至一座公共建筑。第三重“内堤”是一个混合结构，依照海绵城市的原则管理雨水。这层提防实现了将邻近村庄和山区的所有径流缓冲、延迟并临时存放在雨林公园、雨林、森林，湿地和绿道中。

The triple dike moves away from a generic protection wall along the coast, towards the creation of three development zones, carefully embedded in current conditions and responding to the specific future needs of every single area. The 1st ‘outer’ dike zone increases the resiliency through wave attenuation, erosion reduction and the enhance¬ment of sedimentation. The 2nd ‘middle’ dike is an elevated embankment, to stop the storm surge and the water pushed up by the waves. It’s not a big wall but a multifunctional zone: an exciting hilly park, an elevated waterfront with urban promenades, a tidal park or even a public building. The 3rd ‘inner’ dike is a hybrid structure which man¬ages the rainwater following the principle of a sponge city. All runoff from adjacent villages and mountains is buffered, delayed and temporarily stored in rain-parks, raingardens, wet forests, wetlands and green streets.

有效的弹性策略 | A PRODUCTIVE RESILIENCE STRATEGY

大鹏是一个拥有茂密森林，河床和小溪交错，多山的半岛。它与大海相连，拥有梦幻般的沙滩和令人印象深刻的礁岩海岸。它在香港和深圳接壤的地方，提供了非凡的郁葱绿色环境。起始于海防文化，沿岸的小村庄多数靠渔业为生。大鹏的文化资源和自然环境促进了大都市发展区扩张下的旅游业发展。三重海岸防线的应用为增强现有品质的同时释放增长潜力提供了发展框架。在小尺度上，我们通过在现有土地边界内发展新项目的方式来保护村庄的特质。每个村庄的特质都得到了加强，以扩大娱乐设施的丰富性和多样性。为了最大限度地减少对岛屿自然结构性的影响，我们增强了岛屿与海域的连通性。相互连接的山地和海 洋景观促进了半岛的生态功能。

Dapeng is a mountainous peninsula with lush forests, intersected by riverbeds and creeks, connected to the sea with fantastic sand beaches and impressive rockeries. It offers an extraordinary lush and green environment in the direct proximity of Hongkong and Shenzhen. Along the shore, several small villages originate from fishing communities. Dapeng’s cultural resources and natural settings have fostered the development of tourism, within a vast expending metropolitan area with about 20 million inhabitants. The application of the triple-dike provides a framework to enhance these existing qualities while unlocking potentials for growth. The small-scale identity of the villages is protected by locating new developments within the existing boundaries. Each village’s specific character is strengthened to amplify the rich variation of recreational facilities. To minimize the infrastructural impact on the island, connectivity from the water is enhanced. An interconnected mountain and marine landscape boosts the ecological functioning of the peninsula.
