Effects of the excavation of deep foundation pits on an adjacent double-curved arch bridge Open
The excavation of deep foundation pits can cause variations in the displacement and stress fields of surrounding soils, which hence induces adverse effects on adjacent structures. This study presents a two-stage method to quantify the impa…
