Abstract

This article discusses possible variants of underground parking lot in complex engineering and geological environment of St Petersburg, namely: soil excavation in open pit and excavation with solid supports. These methods were analyzed with regard to reasonability for preset construction conditions. A series of predictions were performed using Plaxis 2D software, two variants were described in this article: excavation with the bottom elevation of +0.560 m and excavation with the bottom elevation of -2,500 m and adjacent building (at the distance of 2.5 m). The formulated problems were solved using 2D models. The model was based on the Mohr–Coulomb theory which facilitated estimation of geotechnical environment in the vicinity of the construction. Predictions of retaining wall according to the two considered variants have demonstrated that maximum soil settlement near the excavation is 20 mm and the maximum additional settlement of building at the distance of 2 m from the excavation is 30 mm, which in both cases corresponds to predetermined specifications.
