    岩土材料的流动破坏具有强度突然丧失、变形发展迅速的特点，其过程常伴随着孔隙水压力的快速增高。流动破坏本质上是一种材料失稳行为，可由静力或是动力载荷触发，往往导致灾难性后果。过往的研究使我们逐步了解并掌握了流动破坏的部分特性，然而仍对相当一部分问题未能形成统一的认知，甚至存在混淆与争议。本次曾国熙讲座将围绕这一主题，首先回顾相关研究背景与现状，侧重分析令研究人员与工程师感到困惑的若干关键问题；之后介绍有关流动破坏及相关现象的最新研究成果，以及如何利用这些新认识来指导岩土工程实践。

    杨峻，香港大学教授、土木工程系副系主任；同济大学、浙江大学、上海交通大学兼职/访问教授；美国土木工程师学会（ASCE）香港分会前主席（2010-2011）；香港力学学会副理事长（2020-2022）；中国力学学会特邀理事。拥有浙江大学土木工程学士学位（1992）、岩土工程博士学位（1996）以及日本京都大学地震工程博士学位（2001）。
    研究涉及岩土工程、地震工程及其交叉领域，包括砂土在复杂应力条件下的液化机理、灾害及评估，地震场地效应及多维地震响应分析，土与结构在动力环境下的相互作用机理及实用分析方法开发，岩土颗粒材料多尺度静动力学特性的实验与理论研究，以及离岸及近海工程中的复杂基础工程问题。
    在国际知名学术期刊发表论文120余篇，研究成果被国内外学者广泛引用，并被美国联邦政府及州政府的相关岩土设计指引所引用；美国基本科学指标（ESI）将其列为相关领域世界前1%学者。学术奖励与荣誉包括德国洪堡基金会洪堡学者基金、日本学术振兴会特邀卓越学者基金、中国国家自然科学基金委员会海外与港澳学者合作基金、中国教育部自然科学奖一等奖、中国建设部科学技术奖一等奖、日本土木学会全国大会优秀讲演奖、香港大学杰出青年学者奖以及香港大学杰出研究著作奖。于2012年获选为美国土木工程师学会会士（ASCE Fellow）。

  Flow failure of geomaterials is characterized by a sudden loss of strength and a rapid development of deformation, and is often accompanied by a quick build-up of pore water pressure. It is essentially an instability behavior and can be triggered by either static or dynamic loading. The consequences of this type of failure are often dramatic and catastrophic to our built and natural environment. Typical examples are the massive flow slides of tailings dams, hydraulic fills and submarine slopes. While some aspects of flow failure have been well understood through experimental and theoretical studies over the years, many others, however, remain confusing, controversial or mysterious. This Lecture will first give an overview of the subject, with particular attention on the aspects that confuse researchers and practising engineers. Recent advances in understanding flow failure and related phenomena and the implications for geotechnical engineering practice will then be presented and discussed.

  Dr Jun Yang is a full professor at the University of Hong Kong (HKU) and currently serves as associate head of the Department of Civil Engineering. His research spans a broad spectrum of topics in geotechnical and earthquake engineering, with particular interest in exploring the complex behavior of geomaterials from experimental, theoretical and practical perspectives. He has published extensively in leading journals in his fields, and has been named by Clarivate Analytics among the world’s top 1% scholars by citations. His work has also been referenced in two design guidelines in the US. Professor Yang is an elected Fellow of the American Society of Civil Engineers, the Institution of Civil Engineers, UK, and the Hong Kong Institution of Engineers. Other notable honors include the Humboldt Fellowship of the Alexander von Humboldt Foundation, the Invitation Fellowship of Japan Society for the Promotion of Science, the Natural Science Award (First Class) from Chinese Ministry of Education, and the Outstanding Overseas Chinese Scholars Award from the National Science Foundation of China.
