Abstract:	摘要： This paper presents a new geotechnical design concept, called robust geotechnical design (RGD). The new design methodology seeks to achieve a certain level of design robustness, in addition to meeting safety and cost requirements. Here, a design is considered robust if the variation in the system response is insensitive to the variation of noise factors such as uncertain soil parameters and construction quality. When multiple objectives are considered, a single best design may not exist, and a trade-off may be necessary. In such a case, a genetic algorithm is adopted for multi-objective optimization and a Pareto Front, which describes a trade-off relationship between cost and robustness at a given safety level, is established. The new design methodology is illustrated with an example of spread foundation design. The significance of the RGD methodology is demonstrated. 出版者： Elsevier Ltd 出版日期： 2013-03 出處： Computers and geotechnics, 2013-03, Vol.48, p.96-106 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2012 Elsevier Ltd 識別號： ISSN: 0266-352X 識別號： EISSN: 1873-7633 識別號： DOI: 10.1016/j.compgeo.2012.10.003
