Geosynthetics in Retaining Walls Subjected to Seismic Shaking
https://orcid.org/http://orcid.org/0000-0002-9910-5624
Low tensile strength of soils makes them unsuitable for constructions where soils are subjected to tensile loads. Earthquake loading on soils impose compression and tension loading cycles during which there is a high possibility of failure in geotechnical structures like embankments, slopes and retaining walls. Geosynthetics come to rescue in many such cases where the inclusion of tensile elements in the form of polymeric reinforcement not only reduce the seismic demand on the structures but also provide adequate support to the structures during cyclic loading conditions. This paper presents shaking table studies on unreinforced and reinforced soil retaining walls to demonstrate the beneficial effects of geosynthetic reinforcement under earthquake loading of these structures. Models of wraparound, rigid-faced, segmental and geocell retaining walls were built in a laminar box and tested on a shaking table at different accelerations and frequencies. Results from these tests show that geosynthetic reinforcement can significantly reduce the deformations in these structures and help in avoiding failures.
