An extensive set of in situ and laboratory test data is presented for a footing load test site east of Houston, Texas, in desiccated Beaumont clay. The in situ test program included standard and cone penetration tests (CPTs), the latter of which[...]

To advance the use of reliability-based design procedures, it is necessary to evaluate the sources of the design parameter uncertainty including inherent variability, measurement error, and transformation uncertainty. The results of a probabilis[...]

Experimental studies have observed that the small-strain shear modulus (Gmax) of unsaturated soils measured during hydraulic hysteresis has a greater magnitude during imbibition than during drainage when plotted as a function of matric suction. [...]

This paper reports the results of two centrifuge tests that were conducted to evaluate the effectiveness of colloidal silica for liquefaction mitigation. Colloidal silica has been selected as a stabilizer material in soils because of its permane[...]

In geotechnical engineering, recycled tires are used in lightweight fills, backfill materials, highway embankments, soil reinforcement, and soil-retaining walls. The rubber-soil mixture can exhibit a greater capacity for energy absorbency than s[...]

The behavior of displacement piles in uncemented calcareous sand is investigated using field piles instrumented with a sensor that simultaneously records the radial stress and shear stress at specific locations on the pile shafts. These tests ar[...]

Geomembranes (GMBs) are widely used as advective barriers in landfill liner systems. When exposed to the sun, GMBs exhibit a network of wrinkles as a result of thermal expansion. These wrinkles disrupt the intimate contact between the GMB and th[...]

Hyperbolic model for load tests on instrumented drilled shafts in intermediate geomaterials and rock
Ramesh Chandra Gupta, Auteur
|
Analyses of load tests on instrumented drilled shafts in intermediate geomaterials (IGMs) and rock are performed using a hyperbolic model for relative displacement (Δ)/shaft diameter (d)versus side friction (fs) data. Ultimate side friction (fsu[...]

An algorithm for determining the intersections between fractures is presented in this paper. The algorithm is implemented in GEOFRAC, a stochastic fracture pattern-modeling program. Previously, GEOFRAC allowed one to subdivide a fracture network[...]

The compression behavior of an artificially cemented soil was analyzed by the adjusted porosity/cement index using a correlation established in the recent literature. It was found that for each value of this index, defined as the ratio of porosi[...]
