Study on Calculation Method of Larger Unbalanced Earth Pressure of Backfill behind Abutment in Integral Abutment Jointless Bridges [PDF]

Zhengzhou Daxue xuebao. Gongxue ban, 2022
In order to study the variation of larger unbalanced earth pressure of backfill behind abutment caused by vehicle load, several reciprocating low-cycle pseudo-static tests on interaction of soil-abutment-steel H-pile with or without considering the ...

Effects of Geogrid Reinforcement on the Backfill of Integral Bridge Abutments

Buildings, 2023
The construction of integral bridges is one of the most effective methods to reduce bridges’ construction and in-service costs. However, there are associated geotechnical problems with their abutments backfill due to the integrated abutments.

Application of engineered compressible inclusions to mitigating soil-structure interaction issues in integral bridge abutments

Journal of Rock Mechanics and Geotechnical Engineering, 2023
The thermally induced cyclic loading on integral bridge abutments causes soil deformation and lateral stress ratcheting behind the abutment wall due to the expansion and contraction of the bridge deck.

Subsoil stiffness effects on the bridge-abutment dynamic behaviour [PDF]

E3S Web of Conferences
Integral abutment bridges (IABs) are robust structures that avoid the use of bearings and expansion joints and are relatively maintenance-free compared to conventional bridges.

Numerical Analyses on the Behavior of Geosynthetic-Reinforced Soil: Integral Bridge and Integrated Bridge System

Applied Sciences, 2021
Geosynthetic-reinforced soil (GRS) technology has been used worldwide since the 1970s. An extension to its development is the application as a bridge abutment, which was initially developed by the Federal Highway Administration (FHWA) in the United ...

A Study of the Effects of Geosynthetic Reinforced Soil and Reinforcement Length on GRS Bridge Abutment

Applied Sciences, 2021
The geosynthetic reinforced soil (GRS) bridge abutment with a staged-construction full height rigid (FHR) facing and an integral bridge (IB) system was developed in Japan in the 2000s.

Monitoring of a bridge with integral abutment

IABSE Reports, 2007
<p>Preliminary results obtained from short term test-loading are used to illustrate possibilities of FEM used to calibrate complex interaction characteristics between a pile and soil in a bridge with integral abutments. The measurements are obtained during the winter season on the bridge over Ledån, Northern Sweden.
