Geotechnical Risk and Safety Proceedings of the 2nd International Symposium on Geotechnical Safety and Risk (IS-Gifu 2009) 11-12 June, 2009, Gifu, Japan - IS-Gifu2009

Communication of risks within a transparent and accountable framework is essential in view of increasing mobility and the complexity of the modern society and the field of geotechnical engineering does not form an exception. As a result, modern risk assessment and management are required in all aspects of geotechnical issues, such as planning, design, construction of geotechnical structures, mitigation of geo-hazards, management of large construction projects, maintenance of structures and life-cycle cost evaluation. This volume discusses: 1. Evaluation and control of uncertainties through investigation, design and construction of geotechnical structures; 2. Performance-based specifications, reliability based design and limit state design of geotechnical structures, and design code developments; 3. Risk assessment and management of geo-hazards, such as landslides, earthquakes, debris flow, etc.; 4. Risk management issues concerning large geotechnical construction projects; 5. Repair and maintenance strategies of geotechnical structures. Intended for researchers and practitioners in geotechnical, geological, infrastructure and construction engineering.
