Hong Kong landslip prevention and its social benefits

Abstract

The urban development and infrastructure of Hong Kong are basically built on hillside slopes of 20 to 50 degrees. Landslide hazard is therefore the severest natural hazard phenomenon in Hong Kong. Since 1950s, in particular, since 1975, engineers and researchers in Hong Kong have done tremendous work and investigations in landslide hazard control and mitigation. They have made many significant achievements. Over the many years, they have established a comprehensive methodology on urban landslide hazard management and mitigation. This methodology has been improved and refined during ongoing engineering practice. The efforts have enabled Hong Kong slope safety to become the highest standard in the world. The landslide hazard management and prevention have contributed significantly to the development and prosperities of Hong Kong. Such experience and methodology should benefit to the relevant work in the Mainland China and other cities in the world.

香港市政建設主要是在20°～50°的自然山坡上進行的。滑坡災害是香港最嚴重的自然災害現象。自1950年以來,香港工程師和科研人員在滑坡災害控治方面做了大量的工作和研究,取得了很多重要的成果,在多年實踐中建立了綜合全面性的市區滑坡災害管理體系,並在實際應用中進行完善。這些努力使得香港斜坡安全達到了世界上最高級的標準。香港滑坡災害管理與防治工作為香港的建設與繁榮做出了貢獻,其經驗與技術應有利於內地和世界其他城市的相關工作。
