Quantifying the Effect of Rock Strength Criteria on Minimum Drilling Mud Weight Prediction Using Polyaxial Rock Strength Test Data
(American Society of Civil Engineers, 2006)In engineering practice, a linear poroelasticity stress model in combination with a rock strength criterion is commonly used to determine a minimum mud weight for stable well drilling. Rock strength criterion therefore ... -

Soil–Nail Pullout Interaction in Loose Fill Materials
(American Society of Civil Engineers, 2006)A laboratory study was conducted to investigate the behavior of soil nails embedded in loosely compacted sandy fills. By varying the overburden pressure, the peak pullout force and the load–displacement behavior were ... -
Identification of Poroelastic Constants of “Tight” Rocks from Laboratory Tests
(American Society of Civil Engineers, 2006)This paper discusses the identification of poroelastic constants and hydraulic conductivity from two transient laboratory tests performed on cylindrical core: drained isotropic confinement and pulse test. The combination ... -
Seismic Bearing Capacity of Shallow Strip Footings Embedded in Slope
(American Society of Civil Engineers, 2006)The seismic bearing capacity factors for shallow strip footings embedded in sloping ground with general -
Undrained Bearing Capacity of Square and Rectangular Footings
(American Society of Civil Engineers, 2006)The uniaxial vertical bearing capacity of square and rectangular footings resting on homogeneous undrained clay is investigated with finite element analyses, using both Tresca and von Mises soil models. Results are compared ... -
Drag Force on Single Piles in Clay Subjected to Surcharge Loading
(American Society of Civil Engineers, 2006)Piles driven into clay are often subjected to indirect loading as a result of the surcharge applied on the surrounding area. During the drained period, both the piles and the soil undergo downward movements caused by the ... -
Design and Evaluation of Fiber-Reinforced Polymer Bond-Type Anchorages and Ground Anchors
(American Society of Civil Engineers, 2006)This paper presents laboratory tests on a bond-type anchorage system and a full-scale ground anchor with fiber-reinforced polymer 9-bar tendons. A cement-based mortar filled steel tube was used to simulate a rock mass ... -
Visualization of Crushing Evolution in Granular Materials under Compression Using DEM
(American Society of Civil Engineers, 2006)Granular materials forming part of natural slopes, embankments, subgrades of foundations, and pavement structures are subjected to both static and dynamic loads during their engineering lives. As a result of these loads, ... -
Continuous Interface Elements Subject to Large Shear Deformations
(American Society of Civil Engineers, 2006): In this paper, an interface or joint subject to large shear deformation is modeled. In the proposed algorithm, continuous interface elements with a finite thickness are reconstructed at every load step based on current ... -
Stress Reduction Coefficient and Amplification Factor for Seismic Response of Ground
(American Society of Civil Engineers, 2006)Incorporating the increase of shear modulus with depth -
Relating Damping to Soil Permeability
(American Society of Civil Engineers, 2006)Published comparisons of complex moduli in dry and saturated soils have shown that viscous behavior is only evident when a sufficiently massive viscous fluid (like water) is present. That is, the loss tangent is frequency ... -
Shear Banding in Sandstone: Physical and Numerical Studies
(American Society of Civil Engineers, 2006)The development of a localized damage zone or shear band in rock was studied through numerical and physical experiments. A laboratory biaxial (plane strain) compression test was conducted on a prismatic specimen of Berea ... -
Laplace Boundary Element Model for the Thermoelastic Consolidation of Multilayered Media
(American Society of Civil Engineers, 2006)A boundary-element method for solving the fully coupled equations of thermoelastic consolidation is developed for multilayered media. Conditions of temperature, heat flux, pore pressure, hydraulic flux, displacement, and ... -
Single Hardening Elasto-Plastic Model for Kaolin Clay with Loading-History-Dependent Plastic Potential Function
(American Society of Civil Engineers, 2006)The effect of principal stress rotation on the mechanical behavior of Kaolin clay is investigated using combined axial-torsional tests on hollow cylindrical specimens. The yielding behavior and failure criteria are found ... -
Deformation of Pores in Viscoplastic Soil Material
(American Society of Civil Engineers, 2006)Changes in soil pore volume and shape in response to internal and external mechanical stresses alter key soil hydrologic and transport properties. The extent of these changes is dependent on details of pore shape and size ... -
Automatically Computing the Displacements and Stresses Induced by Three-Dimensional Arbitrarily Shaped Loads in a Transversely Isotropic Medium
(American Society of Civil Engineers, 2006)Since the planes of foundations are not usually regularly shaped, and the loads are often applied on the anisotropic materials, such as transversely isotropic soils or rocks, calculating the induced displacements and ... -
