However, the case for the contiguous pile can be considered as a plain strain problem, so that only the 𝑥-direction toward the excavation remains in the analysis, and that the element stiffness matrix for the problem analysis becomes as: -…”

“…Recently, the method of retaining soil was applied on several underpasses in Dohuk and Mosul governorates when constructing conventional retaining wall becomes useless and disturbing. The method is widely adopted in the aspects of road engineering for the effectiveness and applicability in many developed intersections that cut and cover girder bridges is the main construction components (Chavda et al, 2019). Because of that the recent records of earthquake in the region are become in order of (3) instead of (2B) according to UBC-1997, earthquake design should be importantly included.…”

Recently the usage of Contiguous piles in many different aspects of construction projects are become more common. Determination of the shear force and moment values exerted on the contiguous piles require extensive analysis and calculations especially when earthquake is to be encountered. ANN mathematical models for calculating this value combining 144 input sets that represent height of excavated (H), ratio of H to the depth of embedment (D), unit weight of retained soil ( ) and angle of internal friction ( ) is presented in this paper. The mathematical models obtained show acceptable regression and deviation. It was found that both shear and moment values subjected on the piles are decreases with the decrease of ( ) and increases with the increase of ( ). The height of excavation (H) was found as the most important input parameter that affects the output values of the models

“…The methodology employed in generating these wall configurations is detailed in Section S1. The formulae cover nominal wall heights of 1 m, 2 m, 3 m, 4 m, 5 m, 6 m, 7 m, and 8 m. The FE model was validated against laboratory studies conducted by Chavda et al [20] and Basha et al [21], and the formulae were also applied to an on-site wall test conducted by Li and Lehane [22] and a laboratory study by Bica and Clayton [23].…”

In the current literature, there is no practical formula to calculate the horizontal displacement of cantilever walls. To fill this gap, in the present study, eight formulae for the estimation of wall displacement were developed based on 431 FE wall model configurations. Each formula considers factors such as the wall height, embedment depth, surcharge load, unit weight, internal friction angle, elastic modulus of the surrounding soil, and flexural rigidity of the wall. The FE model, which was used in the development of the formula, was also validated against a physical laboratory study. In addition, the outputs obtained from the formulae were compared with the results of two laboratory studies and a real site study. Finally, a parametric study was performed to estimate the influence of formula input parameters on wall displacement.

“…In practice, pinned or anchored cantilever walls are designed primarily to meet force equilibrium in the limit state. Numerous limit state approaches can be found in the existing literature, such as those proposed by Krey 1932, Blum 1931, Rowe 1951, Brinch Hansen 1953, Padfield and Mair 1984, Yuan et al 2003and Nandi & Choudhury 2019. However, compared to limit-state approaches, there are relatively few studies proposing methodologies for calculating displacements around walls supporting excavations.…”

The design procedure of a free embedded cantilever wall is usually based on limit equilibrium analyses. The wall displacement may play a significant role, especially when the considered wall height is greater than 3 m. In this study, 8 formulas for the estimation of wall displacement were developed based on 431 FE wall model configurations. Each formula considers factors such as wall height, embedment depth, surcharge load, unit weight, internal friction angle, elastic modulus of the surrounding soil, and flexural rigidity of the wall. The FE model, which was used in the development of the formula, was also validated against a physical laboratory study. In addition, the outputs obtained from the formulas were compared with the results of two laboratory studies and a real site study. Finally, a parametric study was performed to estimate the influence of formula input parameters on wall displacement.
