Brinkgreve, R.B.J. (author), Post, M. (author)Displacement-based finite element calculations are primarily used for serviceability limit state (SLS) analysis, but the finite element method also offers possibilities for ultimate limit state (ULS) design in geotechnical engineering. The combined use of SLS and ULS calculations with partial safety factors according to the different design...conference paper 2015

Zhang, Y.-J. (author), Feng, X.-T. (author), Jiang, Q. (author)The epistemic uncertainty and aleatory uncertainty caused by the geology condition and construction method make the surrounding rock stability evaluation of underground cavern group difficult. The first may be reduced with more field investigation, tests or monitoring, but the later can not be avoided completely. So the risk analysis method can...conference paper 2015

Marques, S.H. (author), Beer, M. (author), Gomes, A.T. (author), Henriques, A.A. (author)The first applications of nonprobabilistic interval analysis in geotechnical engineering have been recently explored. In fact, the solution of practical problems in this field often requires judgement based on limited data and interval analysis has become a research area formally motivated by input information characterised by imprecision....conference paper 2015

Wojciechowska, K. (author), Pleijter, G. (author), Zethof, M. (author), Havinga, F.J. (author), Van Haaren, D.H. (author), Ter Horst, W.L.A. (author)The aim of this article is to present and discuss fragility curves that were derived for numerous dikes in the Netherlands within the Dike Data Service Centre (DDSC) initiative. A fragility curve of a dike is a mapping from the set of loads, acting on the dike, to the set of conditional dike failure probabilities. The DDSC is a platform around a...conference paper 2015

Aladejare, A.E. (author), Wang, Y. (author)During geotechnical site characterization, many geotechnical properties might be difficult to measure directly and have to be estimated using indirect measurement and regression models. For example, when there is no possibility of direct compression test, geotechnical engineers and practitioners may utilize regression models (i.e. equations) to...conference paper 2015

Maruyama, O. (author)The numerous major earthquakes in Japan, such as the Great Hanshin-Awaji earthquake, Tohoku Regional Pacific Coast earthquake caused substantial casualties and property damages.

Sanders, M.P.M. (author), Wiggers, A.G. (author)Traditionally Dutch design codes require a minimum distance between a pipeline and the toe of the levee: the ‘safety zone’. The codes provide additional design and maintenance requirements for pipeline sections located within this ‘safety zone’. For existing pipelines, designed before the establishment of the codes, the sections located in the...conference paper 2015

Sutoh, A. (author), Maruyama, O. (author), Kanakiyo, H.T. (author), Sato, T. (author)This paper proposes the tunnel lining deterioration model which is based upon actual inspection data in order to carry out strategic maintenance and to rationalize life cycle cost analysis for tunnel structures. The evaluation value of deteriorating tunnel structures is a non-stationary stochastic process, and reliability problems of such...conference paper 2015

Venmans, A. (author), Schokker, J. (author), Dambrink, R. (author), Maljers, D. (author), Heerema, J.J. (author)This paper presents method and first results of a study to quantify and communicate geotechnical risk for highway construction on soft soil and large building pits associated with infrastructural works in the Netherlands. A set of easy-to-read maps will inform the end users, geotechnical consultants at the Dutch Ministry of Infrastructure and...conference paper 2015

Hoefsloot, F.J.M. (author)In the Bloemendalerpolder two test embankments were constructed, starting October 2010, to study the long term behavior of embankments on very soft soils with respect to settlement and lateral pile loading resulting from horizontal soil deformations. A detailed description of the test embankments, performed soil investigation, laboratory tests...conference paper 2015

Boulware, L. (author), Rice, J. (author)It has long been understood that subsurface geology affects internal erosion potential in levee foundations. Geomorphic features associated with fluvial deposition environments are known to concentrate or block seepage, resulting in sand boils and internal erosion. However, incorporating the effects of geomorphic features into either...conference paper 2015

De Raadt, W.S. (author), Jaspers Focks, D.-J. (author), Van Hoven, A. (author), Regeling, E. (author)The most famous dam of the Netherlands, the Afsluitdijk, is in need of renovation. Hydraulic conditions for the year 2050, for some aspects even 2100, must be considered during the renovation of the dam originally constructed 1927-1933. A combination of sea level rise due to climate change and a change in the applied statistical methods result...conference paper 2015

Baecher, G.B. (author), Christian, J.T. (author)The statistics course most engineers took in college—seldom more than one—introduced them to a particular species of statistics, which, regrettably, is of limited use in geotechnical practice: frequentist sampling theory. That species of statistical thinking arose to address problems of agricultural experimentation, biology, and economics. It is...conference paper 2015

Robbins, B.A. (author), Sharp, M.K. (author), Corcoran, M.K. (author)The U.S. Army Engineer Research and Development Center (ERDC) is conducting research to investigate internal erosion, specifically backward erosion piping, by use of laboratory-scale model testing to understand and properly capture the physics of the problem. Preliminary results show that lower void ratio models, using poorly-graded soils with a...conference paper 2015

Yuan, J (author), Papaioannou, I (author), Straub, D. (author)Landslide events often occur after rainfall events during which the pore water pressure builds up within surficial soil layers, leading to shallow slope failure. The spatial variability of the permeability parameters of the soil causes high gradients in pore water pressure when the rainwater infiltrates into the slope. In this paper, we compute...conference paper 2015
