Performance of inclined-vertical framed retaining wall for excavation in clay
Highlights A high-quality case history of an excavation was introduced and studied. The influences of pile lengths on the deflection were analyzed. The mechanism of the IVFRW was investigated.
Abstract A new strut-free retaining wall system, referred to as an inclined-vertical framed retaining wall (IVFRW), is constructed for excavation in clay. It has been successfully used in engineering practice to limit excavation-induced ground movement and protect adjacent buildings. This paper presents the performance of an excavation constructed by using IVFRW in Tianjin, China. Field investigations indicate that the proposed retaining structures effectively limit the wall deflection. Parametric studies based on the validated three-dimensional finite element model are conducted to improve the fundamental understanding of the mechanism of IVFRW. The influence of the inclined pile and vertical pile lengths on the deformation, internal forces, and wall friction are studied. A concept of neutral plane in retaining wall is proposed, and the mobilization of the skin friction and the axial force linking with earth pressure are analysed. Finally, a design concept for IVFRW is discussed.
