摘要： AbstractThis paper presents a new geotechnical design concept called robust geotechnical design (RGD). This new design methodology, seeking to achieve a certain level of design robustness in addition to meeting safety and cost requirements, is complementary to traditional design methods. Here a design is considered robust if the variation in the system response is insensitive to the variation in noise factors (mainly uncertain soil parameters). To aid in selection of the best design, a Pareto front that describes a tradeoff relationship between cost and robustness at a given safety level can be established using the RGD methodology. The new design methodology is illustrated with an example of drilled-shaft design for axial compression. The significance of the RGD methodology is demonstrated. 出版者： Reston, VA: American Society of Civil Engineers 出版日期： 2013-12-01 出處： Journal of Geotechnical and Geoenvironmental Engineering, 2013-12, Vol.139 (12), p.2007-2019 資源來源： EBSCOhost Academic Search Premier 版權： 2013 American Society of Civil Engineers. 版權： 2015 INIST-CNRS 識別號： ISSN: 1090-0241 識別號： EISSN: 1943-5606 識別號： DOI: 10.1061/(ASCE)GT.1943-5606.0000956
