香港工程師學會 「明日大嶼」願景填海計劃的工程實行性分析 Engineering Perspectives of the Reclamation under Lantau Tomorrow Vision

(香港,二零一八年十一月七日)就社會上持續討論政府所宣佈的「明日大嶼」願景填海計劃,香港工程師學會 (下稱學會)希望就這個能為香港發展帶來重大影響的計劃,從工程的實行性角度去作出分析。

 

實行性關乎計劃的可實施程度,在技術層面上關於填海造人工島的工程技術已非常成熟,世界多個國家及城市過往已有不少成功造島項目的實踐案例,當中包括香港的赤臘角國際機場。事實上已見到這些造島工程項目可通過不同惡劣天氣、海浪高度及水淹的考驗,即使為迎接極端天氣的挑戰的承受能力或有需要加強,亦不難透過考慮興建稍高的海堤或放置弱波石等防禦措施而達到。

 

至於有關對使用填海填料供應的顧慮,其實可供選擇的填料包括有從開山得來的泥土、由海床得來的海砂、人造砂及城市產生的惰性拆建物料等。從工程角度而言,以十多年去計劃和完成千多公頃土地的填海工程,於能合乎環境保護及監管法例要求下,填料不應是解決不到的問題。只需及早規劃,相信可以使填海工程順利進行。聯同適切保護環境的舉措及加固工程設計去控制預計可能發生的填海沉降情況等,這些都不是新遇到的情況,亦非香港過往累積經驗內不可處理及解決的問題。

 

學會期望所作出的分析可以為社會帶來積極與理性的探討,盡快開啟空間,令政府能進一步把這具前瞻性的願景計劃展開更詳盡的可行性研究,包括如財務、城市規劃、環境、交通網絡等,並進行相關前期設計,向市民大眾闡述填海造島計劃較詳細的內容,及怎樣去達至強化香港可拓展的土地住屋及商用空間,改善市民生活質素,推動經濟的增長。因此,學會期望整個社會能夠攜手跨出一步,坐言起行,進取地去增加香港的固有優勢,重燃我們對未來香港的希望。

(7 November 2018, Hong Kong) Noting the heated debate on the Administration's Lantau Tomorrow Vision reclamation initiative, The Hong Kong Institution of Engineers (HKIE) would like to make a rational analysis of this important and impactful initiative. 

 

“Practicality” concerns the suitability of the initiative. In terms of the technical aspects, the engineering technology of constructing artificial islands through reclamation is mature, and has been successfully adopted worldwide, one example of which is the Hong Kong International Airport located at Chek Lap Kok. It has been proven that the challenges of severe weather, height of waves, and flooding have been tackled well in these reclamation projects. To further enhance the resilience of the reclaimed land against future extreme weather scenarios, measures such as building higher sea walls and placement of wave breakers could be adopted. 

 

Resource-wise, available materials for reclamation include excavated quarry, sea sand, artificial sand, or recycled urban construction wastes. With over a decade ahead to plan and complete the reclamation project for more than a thousand hectares of land, and with adherence to environmental protection and monitoring regulations, filling materials should not be an unsolvable problem. Amongst other things, appropriate environmental protection measures and reinforcement designs could also control potential ground settlement issues. These are all old usual issues that have been faced and well tackled in Hong Kong’s engineering projects. 

 

The HKIE hopes the analysis could facilitate constructive and rational discussion, which in turn allows the Administration to take a step further in conducting detailed feasibility studies of the initiative, including its financing plan, urban planning, environment, transport network, to come up with the preliminary designs, which would help the public understand as to how the initiative would create land, housing  and commercial spaces for improving the living standard of Hong Kong and boosting its economy. The HKIE also hopes the society could forge ahead hand in hand to add value to Hong Kong on top of its inherent strength, and bring hope again to future of Hong Kong.
