On design of new energy geotechnical structures: how safe is safe enough?
The development of new energy infrastructures is indispensable to the achievement of a carbon neutral society. However, how to design new energy geotechnical structures reliably and economically is challenging because of the lack of experiences. This presentation will first discuss the challenges involved in the design of new energy geotechnical structures. Then, the safety and reliability of different types of existing geotechnical structures will be compared, which will provide valuable reference for assessing the safety of new energy geotechnical structures. Thereafter, using the design of offshore wind turbine pile foundations as an example, how to quantify and evaluate the safety of a new energy geotechnical structure will be described, through rigorous characterization of the uncertainties and assessment of their effects on the performance of the geotechnical structure. The presentation will also briefly introduce the recent recruitment plan of the department of geotechnical engineering, Tongji University.
