Safety issues, risk analysis, hazard management and control

摘要

The occurrence of hazard events in geotechnical practice is often associated with geotechnicaluncertainties. To prevent hazard events from happening or reduce the impacts of their consequence, sources ofgeotechnical uncertainties need to be identified and treated, and appropriate control measure has to be implementedthroughout a project. The probabilistic methods are the devices dealing with uncertainties and the riskmanagement is the technique to facilitate achieving the goal of project safety. The papers presented in this themeare summarized and briefly discussed in three categories - risk and decision analysis, geotechnical control, andanalysis and control of ground response. In risk analysis, geotechnical uncertainties need to be treated explicitly.Results of risk analysis, qualitatively or quantitatively, not only provide a baseline for decision making but alsoinsights to the problem of concern. In order to make best use of available analysis tools, more case studies areneeded.
