| Abstract: | As a new supporting system for the deep excavation, the shaped steel reinforced soil cement wails formed by Trenr.＇ulting Remixing Deep Wall （TRD） Method have the characteristics of suitable for a wide range of soil conditions, uniform andbomogenous wall shape, and well mechanical and seepage cut off performance. This paper presents a case history of the firstinstallation of TRD wall in the Shanghai and even the deltaic area of Yangtze River in the support of the deep excavation forFengxian Small and Medium Enterprise （SME） Building. The technical details of the TRD method in the design and construclion practice are introduced. |
