Lateral resistance and deflection of rigid walls and piles in layered soils

Abstract

The ultimate lateral resistance and the lateral deflection at working loads of rigid vertical walls and piles with a free head subjected to horizontal load and embedded in two-layered soils of sand and clay have been investigated. Part 1 deals with the behaviour of rigid walls, and the analyses are compared with the results of model wall tests in layered soils. Part 2 treats the behaviour of rigid piles, and the analyses are compared with the results of model tests on piles and pile groups in layered soils and some field case records.

Nonlinear response of laterally loaded rigid piles in sand

“…These ultimate capacities were determined as: (1) the load at which the lateral load -pile head displacement curve becomes linear or substantially linear (Meyerhof et al 1981, Chari and Meyerhof 1983, Prasad and Chari 1996, Lee et al 2010; or (2) the lateral load/moment at a rotation angle of 3.5°-5.5° (Laman et al 1999, Dickin andLaman 2003) or 5° (Haldar et al 2000).

“…Several methods have been developed for predicting lateral capacity of rigid piles based on an assumed profile of soil resistance per unit length along a pile (Brinch Hansen 1961, Broms 1964, Petrasovits and Awad 1972, Meyerhof et al 1981, Fleming et al 2009, Prasad and Chari 1999. The capacity was also determined as the load at a certain displacement from a measured lateral load -displacement or the moment with reference to a specified pile rotation angle from a measured moment -rotation curve (Broms 1964, Haldar et al 2000, Chen et al 2011.…”

Analytical and Numerical Investigations of a Laterally Loaded Single Pile Embedded in a Cohesive Soil

“…These components, in turn, relies on:  Stiffness and strength of the pile  Strength and stiffness of the soil  Head conditions, i.e. fixed or free head Theoretical and numerical techniques have been employed to design and analyse piles exposed to horizontal loads: Barber (1953), Broms (1964), Druery and Ferguson (1969), Banerjee and Davies (1978), Bhushan et al (1979), Poulos and Davis (1980), Meyerhof et al (1981Meyerhof et al ( , 1985, Prasad (1997), McDonald (1999), Phanikanth et al (2012), Hazzar et al (2013) and Mukherjee and Dey (2016). Theoretical approaches are classified into two categories elastic and ultimate load methods.…”
