讲座内容简介
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。

Abstract
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.
About the Lecturer
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.
