Abstract

In this paper the finite element procedure was used to investigate the behavior of 6.1m high Algonquin geogrid reinforced soil retaining wall using the computer program Plaxis under construction and earthquake loading. Algonquin wall was constructed in Algonquin, Illinois by FHWA (Federal Highway Administration).The performance of the wall was measured during the construction using inclinometers and surface optical surveys for deflection, and strain gauges for reinforcement strain distribution. In order to investigate the effect of earthquake loading on the wall performance, the 1994 Northridge earthquake motion was applied as input ground motion in the dynamic analysis. The lateral displacement, reinforcement force and vertical stress under earthquake loading were compared to the end of construction. The results show that there is a reasonable agreement between the instrumentation measurement and the finite element analysis for the reinforcement strain distribution and lateral displacement of the wall, and the vertical stress at the just back of the facing panels is less than γz. Also, the largest lateral displacement due to earthquake loading occurs at the top of the wall.

Numerical Analysis of Algonquin Geogrid Reinforced Soil Retaining Wall under Construction and Earthquake Loading

Arlington, Virginia

In this paper the finite element procedure was used to investigate the behavior of 6.1m high Algonquin geogrid reinforced soil retaining wall using the computer program Plaxis under construction and earthquake loading. Algonquin wall was constructed in Algonquin, Illinois by FHWA (Federal Highway Administration).The performance of the wall was measured during the construction using inclinometers and surface optical surveys for deflection, and strain gauges for reinforcement strain distribution. In order to investigate the effect of earthquake loading on the wall performance, the 1994 Northridge earthquake motion was applied as input ground motion in the dynamic analysis.

The results show that there is a reasonable agreement between the instrumentation measurement and the finite element analysis for the reinforcement strain distribution and lateral displacement of the wall, and the vertical stress at the just back of the facing panels is less than γz.
