Service limit state resistance factors for drilled shafts
The analysis of bored piles, or drilled shafts, at the service limit state is important when foundation settlements are critical to the operation of a structure. The t–z method is a widely used soil–structure interaction model for the analysis of drilled shaft settlement. In current practice, nominal values of soil stiffness and strength parameters are used to determine settlement based upon th...
متن کاملMicroplane damage model for jointed rock masses
The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...
متن کاملSimulation of hydraulic fracturing of jointed rock
This paper presents a modeling approach for three-dimensional simulation of hydraulic fracturing of jointed rock. The base for a successful computer based simulation for productive use is the ability to calculate the fractured volume with sufficient accuracy and efficiency. Especially in cases three dimensional effects have to be taken into account, the common commercial software tools in oil a...
متن کاملShear wave propagation in jointed rock: state of stress
The mechanical characteristics and orientation of joints determine the behaviour of rock masses, including the strength, the stiffness, and all forms of conduction and diffusion. Furthermore, the preferential orientation of joints renders the medium anisotropic. In turn, these properties affect the velocity and damping of propagating elastic waves. The purpose of this study is to investigate th...
متن کاملParametric Study of Steel-Lined Pressure Shafts in Anisotropic Rock
Steel-lined pressure tunnels and shafts are used to convey water from the reservoir to the turbines in high-head hydroelectric power plants. An axisymmetrical multilayer model is often considered by engineers for the design of the steel liner. Stresses and deformations can then be computed with a closed-form analytical solution in isotropic rock. When the rock is anisotropic, the lowest elastic...
