The transportation corridor was closed to traffic for 17 ... -
Algorithms for intelligent prediction of landslide displacements
Liu, Zhongqiang; Guo, Dong; Lacasse, Suzanne; Li, Jin-hui; Yang, Beibei; Choi, Jung Chan (Peer reviewed; Journal article, 2020)Landslides represent major threats to life and property in many areas of the world, such as the landslides in the Three Gorges Dam area in mainland China. To better prepare for landslides in this area, we explored how ... -
Back-calculation of pillar foundation for Skjeggestad Bridge
Bendzovski, R; Hetland, R; Chen, Y; Giese, Steffen; Rosenquist af Åkershult, Anders; Lacasse, Suzanne; Johansen, T; Aabøe, R; Degago, Samson Abate (Peer reviewed; Journal article, 2021)In 2015, a landslide incapacitated the expressway E18 in southern Norway because one of the large foundation pillars of the southern lane of Skjeggestad Bridge near Mofjellbekken failed. This accident immobilised throughway ... -
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 ... -
Data-Fusion Based Vulnerability Analysis of Shield Driven Tunnel Suffering from Extreme Soil Surcharging
Xie, Xin; Huang, Hongwei; Zhang, Dongming; Liu, Zhongqiang; Lacasse, Suzanne (Chapter, 2019)A new data fusion approach is presented for evaluating the vulnerability curves utilizing multi-source monitoring information. A Bayesian network with continuous variables for a shield driven tunnel involving the loading ... -
Evolution of Mass Movements near Epicentre of Wenchuan Earthquake, the First Eight Years
Zhang, Shuai; Zhang, Limin; Lacasse, Suzanne; Farrokh, Nadim (Journal article, 2016) -
GeoSuite Assistance for the Calculation of Settlement
Lacasse, Suzanne; Jostad, Hans Petter; Kim, Yunhee; Liu, Zhongqiang; Sandven, Rolf Birger (Chapter, 2016)As part of the development of the Norwegian-Swedish software GeoSuite, a module with geoassistance was developed and implemented. The paper describes this user-assistance, called "Wizard", helping the user with 1D, 2D and ... -
GeoSuite – A Modular System for Geotechnical Design
Lacasse, Suzanne; Jostad, Hans Petter; L'Heureux, Jean-Sébastien; Torgersrud, Øyvind; Sandven, Rolf Birger (Chapter, 2016)Remarkable advances in the analysis tools of, for example slopes, embankment stability and settlements have happened since the 90s. Many are due to the information technology revolution in all aspects of geotechnical ... -
Hazard, Reliability and Risk Assessment - Research and Practice for Increased Safety
Lacasse, Suzanne (Chapter, 2016)Society increasingly requires the engineer to quantify and manage the risk which people, property and the environment are exposed to. The role of the geotechnical engineering profession is to reduce exposure to threats, ... -
Landslide displacement prediction based on wavelet transform and long short-term memory neural network
Yang, Beibei; Liu, Zhongqiang; Lacasse, Suzanne; Nadim, Farrokh (Chapter, 2019)The prediction of landslide displacement is a key component of an early warning system to mitigate landslide risk. Most of the models for landslide displacement prediction are static models. Yet, landslides move dynamically. ... -
