Abstract:	摘要： This study presents a simplified procedure to quantify the effect of parameter uncertainty with consideration of soil spatial variability in analysis of braced excavations. A well-documented case history is adopted in conjunction with PLAXIS, a proprietary finite element code. The simplified approach based on first-order approximation is easy to use, requires less computational work and provides a practical tool to estimate the variation of the wall and ground responses caused by the uncertainty in input parameters. Moreover, to facilitate the numerical analysis, this study also documents a successful implementation of user-defined soil models, including the hyperbolic and the modified pseudoplasticity soil models, into PLAXIS. The results show that PLAXIS, with these user-defined soil models, can capture the laboratory stress-strain relationships and predict, accurately, the wall and ground responses in a braced excavation. 出版者： Taylor & Francis 出版日期： 2014-02-17 出處： Journal of the Chinese Institute of Engineers, 2014-02, Vol.37 (2), p.141-151 版權： 2013 The Chinese Institute of Engineers 2013 識別號： ISSN: 0253-3839 識別號： EISSN: 2158-7299 識別號： DOI: 10.1080/02533839.2013.781790
