In the foundation pit engineering for an office building of BMW Brilliance in Shenyang, the excavation was pit in the foundation pit with depth of 10.4m and local excavation depth 6.05 to 7.4m, and the adjacent buildings surrounding around. Row piles and rotary jet grouting pile water-stop curtain were adopted as retaining structure and dewatering method to control the deformation. The selection of supporting scheme and the analysis on the construction effects could be the reference to the design and construction of the similar project.
