Cantilever retaining structure, single-pivot mixed retaining structure, borehole cast-in-place concrete pile multi-arch retaining structure are adopled for a certain deep-foundation pit excavation in Nanjing city. Based on the in-situ measured data in excavation and construction of foundation, the time-space effects of deformations of different retaining structures and outside soil under the same engineering geological and hydrogeological conditions and construction condition are studied.
