Seismic Performance of Mechanically Stabilized Earth Wall with Lightweight Aggregate (LWA) Backfill
The paper reports a shake table test on the seismic responses of mechanically stabilized earth (MSE) wall with lightweight aggregates (LWA) backfill. A section of a reduced-scale MSE wall was built in a box that was anchored on the shake table. The MSE wall dimensions were 1.5m high, 1.2m deep, and 1.5m long.Five layers of geogrid were used as the reinforcement. The LWA were compacted at 95% of the maximum dry unit weight at the optimum water content. Scaled 1989 Loma Prieta earthquake excitations were replicated by the shake table. The wrap-around MSE wall was instrumented with accelerometers, linear variable differential transformers (LVDT), linear potentiometers, and dynamic soil stress gauges to respectively record the accelerations, wall vertical settlements, horizontal deflections of wall face, and transient effective stresses during the shaking. The results revealed satisfactory seismic performance of the MSE wall with LWA backfill.
