A system for and method of stabilizing rail track structures using a load transfer apparatus is disclosed. The load transfer apparatus includes a vertical load transfer element with at least one cross-sectional rib and a top load transfer element with at least one longitudinal vertical fin, wherein the top load transfer element is used to transfer applied locomotive and rail car loads to the vertical load transfer element. In one embodiment, the vertical load transfer element comprises a plurality of cross-sectional ribs spaced along a length of the vertical load transfer element. In another embodiment, the top load transfer element comprises a plurality of longitudinal vertical fins spaced along a perimeter of the top load transfer element to enhance stability of the top load transfer element.

Methods for strengthening soils under bases and foundations of buildings and structures with compaction of the base composed of weak mineral soils by determining the optimal design process parameters of the ground piles over the entire area of the base. The essence of the invention is that the method of compaction of bases composed of weak mineral soils that includes formation of a well, filling each well with the compacting material, and creation of a compacting effect on the compacting material by the hollow tubular working tool to form a ground pile. Preliminary engineering and geological surveys of the base area is performed to determine the values of the modulus of deformation, the Poisson's ratio, the internal friction angle, the specific cohesion, the specific gravity, and the initial void ratio of the weak mineral soil.

Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.
