“…From the mechanical compatibility of the overall retaining structure, substituting Equations ( 13)-( 17) and (21) into Equation (22), the asymmetric lengths of the walls on both sides in asymmetric excavation, denoted as L 1 and L 2 , can be obtained:…”

“…In addition, a deformation-based design method is required to mee stricter deformation requirements of excavations to protect existing neighboring struc tures. Existing analytical and semi-analytical methods for designing the embedmen depth of retaining structures [18][19][20][21] primarily concentrate on excavations with a single depth. Gajan [18] presented a method for calculating the embedment depths of cantilever walls and walls propped at crests.…”

“…Considering the earth pressure distribution mode in a non-ultimate state, Conte et al [19] developed a deformation-based method for calculat ing the embedment depth of a cantilevered retaining wall. Nandi and Choudhury [20,21 proposed a deformation-based design method for embedded cantilever retaining walls with and without a surcharge. However, these prior analytical methods are mainly appli cable to deformation-based design of cantilever retaining walls and cannot accommodate asymmetric excavation depths.…”

Conventional methods for designing retaining structures are not applicable to asymmetric excavation or deformation-based designs. This study proposes a quadruple-line displacement-dependent earth pressure coefficient model. Based on the proposed model, an analytical solution was developed to facilitate the deformation-based design of the asymmetric length of retaining walls propped at the crest. Furthermore, the effects of the soil internal friction angle, strut stiffness, excavation asymmetry level, and deformation control value on the embedment ratio (Re) of retaining walls were investigated. The results showed that Re determined by the classical equivalent-beam method is unsafe due to its basis on the ultimate-state earth pressure theory. The Re value of the shallower side exhibited greater sensitivity to asymmetric excavation than that of the deeper side. The retaining structure’s required Re decreased with an increase in the excavation asymmetry level. The required Re on either side of the retaining structure decreased as the deformation control values increased. The controlled deformation had a more obvious effect on the Re value of the retaining structure on the deeper side. The proposed method can be used for the deformation-based design of asymmetric wall lengths of retaining structures propped at the crest, considering the different excavation depths on both sides.

“…However, it is widely recognized that the ground movements induced by excavations can affect adjacent structures [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Therefore, in order to avoid any potential damage to the adjacent properties and improve the sustainability of the neighboring environment, the concept of performancebased design has been adopted since the 1990s, which emphasizes the importance of deformation control in the design of retaining walls [17][18][19][20][21][22].…”

Displacement control is critical to the design of retaining walls, especially in urban areas, to avoid any potential damage to adjacent structures during excavations. In this study, model tests are first conducted to investigate the stress and deformation mechanisms of an embedded cantilevered retaining (ECR) wall during excavations. The development of the wall top displacement and the active and passive earth pressures acting on the ECR walls during excavations are studied. Upon the experimental observations, a displacement-dependent earth pressure coefficient is proposed to derive an analytical solution to predict both the active and passive earth pressure acting on the ECR wall (pile), where the displacement value and displacement mode of the ECR wall (pile) are taken into account. Comparisons between the model predictions and test results are carried out. A good agreement is observed, which shows the validity of the proposed solution. Based on the proposed solution, a displacement-controlled method for the design of ECR walls (piles) that takes into account the location of the rotation point is proposed. Parametric studies are conducted to demonstrate the impact of deformation control and excavation depth on the design parameters of ECR walls (piles).
