Bestemmelse av hviletrykk (K0) i norske leirer – anbefalinger basert på en sammenstilling av lab-, felt- og erfaringsdata
L’Heureux, Jean-Sébastien; Ozkul, Zeynep; Lacasse, Suzanne; D'Ignazio, Marco; Lunne, Tom (Chapter, 2017)The purpose of this study is to present guidelines and correlations to estimate the coefficient of earth pressure at rest (K0) in Norwegian clays in absence of site-specific data. A database of K0-measurements from advanced ... -
Characterization of method Uncertainty for Axial Pile Design
Liu, Zhongqiang; Nadim, Farrokh; Lacasse, Suzanne (Chapter, 2018)The paper describes two approaches for deriving the mean, standard deviation and probability density function of the method uncertainty for an axial pile capacity calculation method. The focus of this paper is on estimating ... -
Comparison of analytical and numerical design of suction anchors in deepwater clays
Choi, Young Jae; Schrøder, Knut; Lacasse, Suzanne (Chapter, 2017)The paper presents the result of an extensive study on the undrained holding capacity of suction anchors with different length-to-diameter ratios. The clays used in this study have a linearly increasing undrained shear ... -
