“…The upper part of the plot is enlarged for clarity. In general terms, the displacement of each wall type is similar, with differences in the maximum displacement value of less than 0.8 mm (4.6%), and within the order of magnitude of displacements of the reference case (Carrubba, Colonna 2000).…”

“…A numerical rather than a simplified model is necessary, as the constructive sequence is considered (Carrubba, Colonna 2000), which includes the cross-section changes that take place when the SFRC is sprayed, together with general wall and soil properties. The literature contains many studies that utilize these models to analyze ground movements caused by deep excavations, due to their importance in the prediction of possible damage to adjacent buildings during excavation process (e.g., (Hsiung, 2009;Khoiri, Ou, 2013;Kung et al 2007;Kung 2009)).…”

“… BL 55+10 : Bi-layer RC wall with a thickness of 55 cm onto which a 10 cm thick SFRC layer is sprayed. The general characteristics of the walls used in this study are similar to those used by Carrubba & Colonna (2000), in order to contrast our results with others from the technical literature. Apart from some minor differences, a major difference is the increase in the penetration depth of the walls.…”

Abstract. The bi-layer diaphragm wall, a new slurry wall type designed to cope with the problem of watertightness is studied in this paper. These walls consist of two bonded concrete layers, the first, a conventional Reinforced Concrete (RC) diaphragm wall, and the second, a Sprayed Steel Fibre Reinforced Concrete (SFRC). The main objective of this paper is to analyze the structural and sectional behaviour of these walls. A study in the form of an uncoupled structuralsection analysis based on various hypothetical cases of bi-layer diaphragm walls was performed to fulfil the objective. It is concluded that there exists a potential of reduction in the reinforcement of the RC layer through the structural use of the SFRC layer. However, when the reduction is quantified, even though a reduction of between 3.2% and 1.7% in the RC reinforcement is confirmed, it appears insufficient to offer a cost-effective solution. Nonetheless, the system becomes a promising solution when particular conditions are taken into account, such as basement space limitations.
