项目摘要

Tsunami waves are catastrophic events which can adversely impact communities located in often heavily populated coastal areas around the world, including Canada. Tsunami-induced coastal flooding often leads to numerous casualties and tremendous economic losses. Such extreme waves can propagate thousands of kilometres away from their generating source. Since 80% of tsunamis in the world have occurred in the Pacific Ocean, the western coast of Canada is particularly under threat of tsunami waves attack.** Understanding the impact mechanisms and properly understanding the nature of tsunami-induced extreme hydrodynamic forces on coastal infrastructure and quantifying them is essential because of the enormous economical and social consequences that are characteristic of such disasters. An extensive literature review of the state-of-the-art research on tsunami forces on structures presented by Nistor et al. (2009) indicated that, to date, design documents or building codes that specifically address tsunami loading on near-shoreline structures are lacking.** Therefore, this proposal is focused on the detailed investigation and accurate quantification of tsunami-induced extreme hydrodynamic forces and their impacts on structures by means of: (1) a comprehensive experimental research program focusing on the impact of tsunami-induced hydraulic bores on structural elements and (2) the development of a new mathematical and numerical model capable of accurately simulating the magnitude and transient nature of these hydrodynamic forces, as well as the induced loading on structures. Two MASc students and three Phd studens will work on this research topic** The results of this research project, unique in Canada and one of the few in the world, will ultimately lead to the development of new, reliable design guidelines and tools that will be used by engineers and coastal zone managers and planners to properly design coastal infrastructure located in tsunami-prone areas.******************

海啸波浪是灾难性事件，可能会对位于世界各地（包括加拿大）的沿海地区经常受到不利影响。海啸引起的沿海洪水通常会导致许多伤亡和巨大的经济损失。如此极端的波浪可以远离其生成来源数千公里。由于世界上有80％的海啸发生在太平洋中，因此加拿大西部海岸尤其受到海啸浪潮攻击的威胁。对Nistor等人提出的关于结构的最先进的海啸力量研究的文献综述。（2009年）表明，迄今为止，缺乏专门针对海啸载荷的设计文档或建筑规范。元素和（2）开发了一个新的数学和数值模型，能够准确模拟这些流体动力的大小和瞬态性质，以及在结构上的诱导载荷。 Two MASc students and three Phd studens will work on this research topic** The results of this research project, unique in Canada and one of the few in the world, will ultimately lead to the development of new, reliable design guidelines and tools that will be used by engineers and coastal zone managers and planners to properly design coastal infrastructure located in tsunami-prone areas.******************
