The subject invention pertains to a method and apparatus for inducing a lateral load for the purpose of increasing the force needed to lift a pile and/or increasing the downward and/or lateral load bearing capacity of a pile. The pile can be a driven or pushed displacement pile, a driven or pushed non-displacement pile, any type of bored pile, or any combination. In an embodiment, the subject invention can enhance pile performance by increasing (prestressing) permanently the lateral pressure between a pile and its surrounding soil. The subject invention can provide directional displacement through induced lateral loading of installed piles. Embodiments of the subject invention can incorporate embedded lateral loads in one or more piles.

A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

Lateral extensions enhance the capacity and stability of a foundation element by penetrating the surrounding substrate creating a stronger underpinning. The load bearing capacity of a foundation element is increased by deploying extensible components into the surrounding substrate/soil. The breadth of a foundation element is expanded by extending components into the surrounding soil via an expansion mechanism integrated within a foundation element or piling and deployed into the surrounding substrate once the foundation element is positioned in the ground.

A foundation having a central vertical pedestal, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal and ribs forming a continuous monolithic structure. An anchoring system under the ribs with anchoring the foundation to the ground by anchoring elements connected to rock anchors, soil anchors, piles or the like. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

A modular slab, slab system, piles and methods of use thereof are described along with specific applications and methods of manufacture. The slab or slab system may be pre-insulated and pre-finished before being assembled on site. The slab system may be advantageous to use as a replacement for traditional in-situ poured building foundations. The slab system may also have uses in other fields such as for floors, roads, bridges, pavements/side walks and other civil and structural applications.

A ground improvement body includes a horizontal plate-shaped upper improvement body and a lattice-shaped lower improvement body. The depth of the lower improvement body is gradually increased from an outer peripheral part of the ground improvement body toward a center part of the ground improvement body. Thus, ground contact pressure of the ground improvement body is balanced between its outer peripheral part and center part.
