Time-Dependent Behavior
This paper is a report of the material presented at the International Workshop on Finite Element Analysis of Reinforced Concrete, Session 4 - Time Dependent Behavior, held at Columbia...
Lime Sludge Amended Fly Ash for Utilization as an Engineering Material
Sludges generated from various water treatment operations are predominantly subject to the fate of land disposal. To prepare sludges for land disposal typically requires time consuming...
Treatment of Calcareous Expansive Clays
The geology, climatic condition and the environment of extreme disintegration, strong hydration and restrained leaching have a large influence on the formation of expansive clays in the...
Lateral Loading Curves from Pressuremeter Tests
The large drilled shafts for the proposed Klamath Falls Bridge, which are to be founded in diatomaceous silts, were to be designed to withstand earthquake induced large cyclic loading....
Drilled Shaft Side Resistance in Clay Soil to Rock
An evaluation is made of available field load test data for the axial side clay soils to hard rocks. Conventional total stress interpretations by the alpha method are used to examine the...
Load Testing of Permanently Cased Drilled Shafts Founded in Hartford Shale
The axial and lateral load testing of three, 30 inch (76cm) diameter, permanently cased drilled shafts is analyzed herein. The prototype shafts were founded in (or on) Hartford Shale bedrock,...
Perimeter Load Transfer in Drilled Shafts in the Eagle Ford Formation
Results of six full-scale compression loading tests at four sites in the Dallas area are considered. Compressive strengths (qc) of the rock varied...
Side Resistance of Drilled Shafts in the Denver and Pierre Formations
Results of load tests on drilled shaft foundations in Upper Cretaceous shales are described and evaluated. Three load tests were conducted on shafts in the Denver Formation, in Denver,...
Behavior of Instrumented Model Piers in Manufactured Rock with a Soft Layer
A laboratory test apparatus has been used to study the side resistance of piers socketed into manufactured soft-rock masses. The results of four tests are reported, three of which included...
Transmitted Swelling Pressures on Retaining Structures
The main objectives of this paper are to describe a finite element model to simulate the lateral swelling behavior of expansive soils as a function of soil suction change in the soil domain...
Osmotic Suction as a Valid Stress State Variable in Unsaturated Soil Mechanics
The hypothesis of the research being presented is that the osmotic suction of soil pore fluid is an independent, valid stress sate variable for unsaturated soils. A review of concepts...
Modelling the Behaviour of Compacted Soils
Predictions based on a recently developed model for unsaturated soil behaviour have been compared with some results of two experimental programs on compacted soils recently published in...
On the Elasto-Plastic Behavior of an Unsaturated Silt
Due to technical difficulties related to the control and measurement of the suction in unsaturated soils, few experimental data on the mechanical behavior of those soils exits. The paper...
Elasto-Plastic Volume Change of Unsaturated Compacted Clay
Isotropic compression tests were performed on samples of unsaturated compacted kaolin in a modified triaxial cell that allowed separate control of pore water pressure and pore air pressure....
One and Three Dimensional, Three Phase Deformation in Soil
An initially saturated soil exhibits two distinct deformation patterns as it drys. First, it deforms vertically until the soil begins to drain. Secondly , it deforms laterally as well...
Flow Properties of Unsaturated Soils Under Controlled Suction
Laboratory tests were performed for the hydraulic characterization of three compacted soils under high suction. Moisture changes were studied considering some factors affecting the time...
Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...
Data Base for the Design of Piers in Expansive Soils
The paper describes the parameters and the structure of the seed of a data base of properties and observed field behavior of expansive soils assembled from an extensive literature review....
