Standing J.R. , Potts D. M. et al.
<p>A major research project investigating the effect of tunnelling on existing tunnels has been completed at Imperial College London. This subject is always of great concern during the planning and execution of underground tunnelling works in the urban environment. ...

NUMERICAL MODELLING OF RAPID, FLOW-LIKE LANDSLIDES ACROSS 3-D TERRAINS: A TSUNAMI SQUARES APPROACH TO EL PICACHO LANDSLIDE, EL SALVADOR, SEPTEMBER 19, 1982 (2015)
Wang J. , Ward S. N. et al.
<p>Flow-like landslides are rapidly moving fluid–solid mixtures that can cause significant destruction along paths that run far from their original sources. Existing models for run out prediction and motion simulation of flow-like landslides have many ...

A COMPARISON BETWEEN THE RESULTS OF THE NUMERICAL AND EXPERIMENTAL ANALYSIS OF PULL-OUT STRENGTH OF GEOGRID AND GRID-ANCHOR SURROUNDED BY COARSE SOIL LAYER IN COHESIVE SOIL (2014)
<p>The pull- out strength of the reinforcement has a significant role on the function of the most reinforced soil structures. Since the coarse grain soils have a better interaction with the reinforcement, they are mostly used in these structures. In most situations, ...

METHODOLOGY FOR ESTIMATING SEISMIC COEFFICIENTS FOR PERFORMANCE-BASED DESIGN OF EARTHDAMS AND TALL EMBANKMENTS (2014)
Papadimitriou A. G. , Bouckovalas G. D. et al.
<p>Following an overview of pertinent literature, this paper presents a new methodology for estimating seismic coefficients for the performance-based design of earth dams and tall embankments. The methodology is based on statistical regression of (decoupled) ...

ROCK MASS CHARACTERIZATION AND CONCEPTUAL MODELING OF THE PRINTZSKÖLD OREBODY OF THE MALMBERGET MINE, SWEDEN (2013)
Umar S. B. , Sjöberg J. et al.
<p style="text-align: justify;">The LKAB Malmberget Mine is mined using sublevel caving. This mining method is cost-effective but results in successive caving of the host rock and mining-induced ground deformations. Consequently, re-locations of residential ...

<p>Observations of the performance of many different types of retaining structures in recent earthquakes show that failures of retaining structures, including braced excavation supports and basement walls, are rare even if the structures were not designed ...
Filed under: Earthquake Engineering - Seismic Soil - Structure InteractionReference: STATE OF CALIFORNIA DEPARTMENT OF TRANSPORTATION TECHNICAL REPORT 65A0367
Reyes-Montes J. M. , Sainsbury B. et al.
A case study is presented using Northparkes Mine microseismic (MS) events located by forward calculating P- and S-wave travel times using ray-tracing and wavefront construction techniques through velocity structures that mimic heterogeneity and damage in the ...
Filed under: Mining Engineering - Mine Numerical AnalysisReference: Proceedings 6th Int. Conference and Exhibition on Mass Mining, Massmin 2012. Sudbury, Ontario, Canada, June 10-14 2012.
This dissertation contributes to the improvement of the predictive accuracy of the impact capacity of rockfall protection galleries and to the establishment of a performance-based design procedure for these structures. Furthermore, it facilitates the understanding ...

NUMERICAL TREATMENT OF TWO-PHASE FLOW IN CAPILLARY HETEROGENEOUS POROUS MEDIA BY FINITE-VOLUME APPROXIMATIONS (2012)
This paper examines two-phase flow in porous media with heterogeneous capillary pressure functions. This problem has received very little attention in the literature, and constitutes a challenge for numerical discretization, since saturation discontinuities ...
Filed under: Soil Mechanics - Numerical MethodsReference: International Journal of Numerical Analysis & Modeling;2012, Vol. 9 Issue 3, p505
This paper presents a parametric investigation of the seismic response of circular tunnel. The dynamic response in non-linear conditions due to seismic shaking is analysed numerically making use of the finite element program ICFEP in non-linear conditions. ...
