Bearing failure modes of rock foundations with consideration of joint spacing

Simulation of Characteristic of Linear Degradation with Failure Modes

Reliability of Shallow Foundations Designed Against Bearing Failure Using LRFD

There is a growing interest world-wide in the development of a rational reliability-based geotechnical design code. The reason for this interest is a least two-fold; first of all, geotechnical engineers face uncertainties which are commonly significantly larger than those faced in other fields of engineering and so there is a need to properly characterize and deal with this uncertainty. Secondl...

Interconnect sizing and spacing with consideration of couplingcapacitance

This paper studies interconnect sizing and spacing (ISS) problem with consideration of coupling capacitance for performance optimization of single or multiple critical nets. We introduce the formulation of symmetric and asymmetric wire sizing. We develop efficient bound computation algorithms for ISS optimization and prove their optimality under general interconnect resistance and capacitance m...

Numerical modeling of the effects of joint hydraulic aperture, orientation and spacing on rock grouting using UDEC: A case study of Bakhtiary Dam of Iran

This study aims at presenting a numerical model for predicting grout flow and penetration length into the jointed rock mass using Universal Distinct Element Code (UDEC). The numerical model is validated using practical data and analytical method for grouting process. Input data for the modeling, including geomechanical parameters along with grout properties, were obtained from a case study. The...

Simulation of rockfall trajectories with consideration of rock shape

The aim of the paper is to develop a fully 3D simulation technique for rockfall dynamics taking rock shape into account and using the state-of-the-art methods of multibody dynamics and nonsmooth contact dynamics. The rockfall simulation technique is based on the nonsmooth contact dynamics method with hard contact laws. The rock is modeled as an arbitrary convex polyhedron and the terrain model ...
