Passive Force-deflection Behavior for Abutments with MSE Confined Approach Fills
Author: Kyle M. Rollins
Publisher:
ISBN:
Category : Reinforced soils
Languages : en
Pages : 88
Book Description
Approach fills behind bridge abutments are commonly supported by wrap-around mechanically stabilized earth (MSE) walls; however the effect of this geometry on passive force development is unknown. This report describes the first large-scale tests to evaluate passive force-deflection curves for abutments with MSE wingwalls. A test was also performed with fill extending beyond the edge of the abutment wall for comparison. The abutment wall was simulated with a pile supported cap 5.5 ft high, 11 ft wide, and 15 ft long in the direction of loading. The backfill behind the pile cap consisted of clean sand compacted to 96% of the modified Proctor maximum density. As the pile cap was loaded laterally, pressure on the MSE wall led to pull-out of the steel reinforcing grids and the MSE wall panels moved outward about 2% of the wall height when the ultimate passive force developed. Despite pullout, the passive force per effective width was 28 kips/ft for the pile cap with MSE wingwalls compared to 22.5 kips/ft for the cap without wingwalls. Nevertheless, the passive force with the MSE wingwalls was still only 76% of the resistance provided by the cap with fill extending beyond the edges. The pile cap with MSE walls required greater movement to reach the ultimate passive force (deflection of 4.2% of wall height vs. 3%). The Caltrans method provided good agreement with the measured passive resistance while the log spiral method required the use of a higher plane strain friction angle to provide reasonable agreement.

Subsurface Conditions
Author: Michael Shaw Rosenbaum
Publisher: Springer Science & Business Media
ISBN: 3540437762
Category : Science
Languages : en
Pages : 418
Book Description
Characterisation of the shallow subsurface provides civil, geotechnical and environmental applications with precise definitions of geomechanical and geohydrological properties. Over the past decade, the rapid pace of technological innovation has outstripped the ability of many researchers and potential users to evaluate and adopt promising new characterisation methods. Modern information technologies and information management concepts provide the basis of new paradigms and applications. This book defines future research needs for geological modelling and ground characterisation, including better dialogue between data provides and users and faster, better and less expensive methods for the creation and dissemination of subsurface characterisations.

Languages : en
Pages : 400
Book Description
Piling is a fast-moving field and in recent years there have been major advances in theory, methods, testing procedures and equipment. Some of these changes have been driven by the need for economies by improved efficiency, reduced spoil production and new methods of pile bore support. Advances in theoretical analyses allow pile design to be refined so that piles and pile groups perform to better advantage.
