Abstract: As a new supporting system for the deep excavation, the shaped steel reinforced soil cement walls formed by Tren Cutting Remixing Deep Wall (TRD) Method have the characteristics of suitable for a wide range of soil conditions, uniform and homogenous wall shape, and well mechanical and seepage cutoff performance. This paper presents a case history of the first installation of TRD wall in the Shanghai and even the deltaic area of Yangtze River in the support of the deep excavation for Fengxian Small and Medium Enterprise (SME) Building. The technical details of the TRD method in the design and construction practice are introduced.
