Modern large scaled buildings are erected on rather complex foundations. The design and analysis of these geotechnical systems requires a high quality of computer modelling and simulation. Therefore, it is necessary to model all geotechnical structural elements in a realistic and practice-oriented way. Due to the complexity of geotechnical structures object-oriented models are most appropriate....

The geotechnical literature is not exempt from oxymorons. For example, analytical solutions for interparticle contact clearly show that soils and all particulate materials are inherently non-linear -Hertz theoryand non-elastic -Mindlin’s theory (See Richart, Hall and Woods, 1970; Cascante and Santamarina, 1996). Yet, “linearelastic soil behavior” is a common expression. In most cases it refers ...

A new contact bond model based on the Mohr-Coulomb failure criterion has been implemented in PFC2D to reproduce the behaviour of frictional cohesive (c, φ) geomaterials. According to this model, the bond strength can be clearly divided into two distinct micromechanical contributions: an intergranular friction angle and a cohesive bond force. A parametric analysis has been run to validate the pr...

Karst is geomorphologically composed of limestone. However, limestone very susceptible to weathering due the influence water, which can cause land subsidence. The resistivity method often used determine potential for subsidence, while geotechnical methods are commonly considered capable juxtaposing with support interpretation accuracy. current research was conducted subsidence in karst area Lap...

In this research, a new method is proposed to update system reliability based on data recorded by instruments and sensors installed on geotechnical systems to reduce uncertainties. The method is founded on Bayesian analysis and Monte Carlo simulation and is capable of estimating the functional relationship between the updated failure probability and the monitoring value. It is shown that as lon...
