“…When the geometry of the ground of the soil ground increases, the capacity reduces to a maximum of 37.5%; but the influence was negligible for a smaller slope (1 V:5H) [79]. When a rigid pile-group is installed in slope crest, the depth of fixity of the leading pile is higher than the single pile with fixed head [80].…”

“…The effect of slope is negligible when the ground inclination is less than 11.3°( [79,91]) and the influence of slope is neglected below the depth of fixity [92]. The effect of eccentricity in sloping ground is also studied, where reduction in capacity is mainly due to rigidity of the pile which decreases with reduction in depth of embedment [93].…”

“…However, research reported on laterally loaded piles embedded in clayey soil or multilayered soil deposits mostly consider stiff clays or soils possessing a considerable amount of stiffness modulus [10,13,17]. A limited work has been reported on laterally loaded piles embedded in soft clay [21,22]. However, research data on behavior of laterally loaded piles in layered soil consisting of soft clay at liquid limit overlying dense sand is still meager.…”

This paper presents the results of three dimensional finite element analysis of laterally loaded pile groups of configuration 1×1, 2×1 and 3×1, embedded in two-layered soil consisting of soft clay at liquid limit overlying dense sand using Plaxis 3D. Effects of variation in pile length (L) and clay layer thickness (h) on lateral capacity and bending moment profile of pile foundations were evaluated by employing different values of pile length to diameter ratio (L/D) and ratio of clay layer thickness to pile length (h/L) in the analysis. Obtained results indicated that the lateral capacity reduces non-linearly with increase in clay layer thickness. Larger decrease was observed in group piles. A non-dimensional parameter Fx ratio was defined to compare lateral capacity in layered soil to that in dense sand, for which a generalized expression was derived in terms of h/L ratio and number of piles in a group. Group effect on lateral resistance and maximum bending moment was observed to become insignificant for clay layer thickness exceeding 40% of pile length. For a fixed value of clay layer thickness, lateral capacity and bending moment in a single pile increased significantly with increase in pile length only up to an optimum embedment depth in sand layer which was found to be equal to three times pile diameter and 0.21 times pile length for pile with L/D 15. Scale effect on lateral capacity has also been studied and discussed. Doi: 10.28991/cej-2021-03091686 Full Text: PDF

“…Extensive research has been carried out by Broms [3], Prakash and Kumar [26], Gandhi and Selvam [8], Muthukkumaran et al [21], Begum et al [1], Chandrasekaran et al [5], Muthukkumaran [22] and Deendayal et al [7] theoretically and experimentally to study the behaviour of the pile on clayey and sandy soil under lateral load. A limited number of instrumented load tests have been conducted for studying the response of pile socketed onto rock strata subjected to lateral load.…”

Large diameter rock socketed piles were preferred for the purpose of transmission of a huge volume of both vertical and lateral load from superstructure to a deeper depth safely without any structural defects. A series of experimental program was conducted on model pile for studying the behaviour of the rock socketed pile under static lateral load in a soil-rock layered profile system. The model piles were instrumented with displacement and force transducers for measuring the magnitude of the pile movement and load transferred by the pile. The experimental results showed that the rock socketed pile lateral capacity has significantly affected by the depth of embedment of the pile in soil and depth of rock socket. There was a considerable increase in the lateral capacity of the pile when the depth of socketing is three times the diameter of the pile into rock with a minimum embedment. In the 3D socketed piles, the lateral capacity of the pile is almost 18 times higher than the non-socketed piles. From the experimental study, it is also observed that when the piles socketed more in to the hard strata (rock), the depth of fixity increases and the lateral displacement reduces substantially.
