Abstract

In current study, firstly the soil-nailed wall of the Seattle area of Washington was modeled by PLAXIS 2D software. After validating the numerical model, the effect of adjacent surcharge distance from the excavation edge on the static and seismic performance of the soil-nailed wall was investigated. The results of numerical analysis indicated that the maximum value of shear force of the wall is created in the place of nails, and with the increase of depth, the value of shear force has increased, which was proportional to the distribution of the soil lateral pressure relative to the wall, which is in triangular. The results of the analyses showed that by changing the distance of the surcharge from the excavation edge, the values of the force component in the nails and as a result, the stability of the wall are affected. In addition, in foundations close to the excavation, the issue of differential settlement caused by the location of wedge failure is a very important parameter and should be considered by designers.
