Remediating a soil-nailed excavation in Wuhan, China Available to Purchase

Soil nailing was employed to stabilise the sides of a basement excavation in an urban district of Wuhan City, China. During the course of the excavation, excessive movements were observed, and collapse occurred along one of the basement sides. A remedial earth-retaining system was developed to provide additional stability to the ground retained by the soil-nailed wall. In the revised system, the soil-nailed wall retained the upper soil while propped piles at the toe of the wall augmented the overall stability of the sides. The case study presented in this paper demonstrates the effectiveness of the earthretaining system in controlling movements.
