Stabilization of South Texas Soils with Fly Ash
The expansive soils of south Texas have traditionally been stabilized with lime or Portland cement. As an alternative, a class F fly ash was tried to stabilize expansive soils obtained...
Enzyme Enhanced Stabilization of Soil and Fly Ash
The purpose of this research was to determine if enzymes could be utilized to increased the strength and stability of soil mixed with fly ash. Samples were prepared with and without 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....
Evaluation of Dilatometer Method to Determine Axial Capacity of Driven Model Pipe Piles in Clay
The flat Dilatometer (DMT) provides a unique approach to estimate the effective stress axial capacity of driven displacement piles in clay. An investigation using this approach was performed...
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,...
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...
The Transistor Psychrometer: A New Instrument for Measuring Soil Suction
The transistor psychrometer is the latest instrument available for the measurement of soil moisture suction. It has been developed over a number of years and is very similar in operation...
Fly Ash for Soil Improvement
This proceedings,
A Better Grade Of Grade
A new technique for using geogrid reinforcement to construct natural-looking steep earth slopes called landform contour grading helped meet engineering, economic and aesthetic challenges...
Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....
Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
The 1984 Major Rehab of the Muskegon Harbor, MI South Breakwater: An Extreme Example of Misguided Design of a Stone Structure
It can be inferred from the Shore Protection Manual that the stability of any coastal structure is increased in proportion to the weights of the armorstones. The south breakwater at Muskegon...
Subaqueous Disposal Area Development and Mitigation
Development of subaqueous dikes on soft soils extensively utilized geosynthetics. The design adopted a wide-bermed embankment with high-strength geotextile for tensile reinforcement and...
Dutch Experience on Design of Dikes and Revetments
The increased demand for reliable design methods for protecting structures has resulted in The Netherlands in preparing a set of design guidelines for design of dikes and revetments. The...
Grouting, Soil Improvement and Geosynthetics
The proceedings of the 1992 ASCE Specialty Conference on Grouting, Soil Improvement and Geosynthetics, addresses advances in the state-of-practice, research and technological developments...
On the Influence of Seismically Induced Residual Forces on Bridge Abutment Design
The seismic design of bridge abutments depend on the anticipated movement of the abutment during the design earthquake. For seat-type abutments in which the backfill resistance can be...
Instability of Slopes with Nonassociated Flow
Experimental investigations of the conditions for instability have shown that granular materials may become unstable inside the failure surface. For states of stress below the failure...
Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...
Transient Analysis of Flexible Space Structures
A new approach for numerical analysis of flexible space frames subjected to impact forces is presented. The method is particularly effective in the analysis of large amplitude vibration...
