In this article the variants of application of pile foundations of C-1 (6,5m) and C-2 (9,3m) type according to the standard project "Album of recommended solutions for installation of contact network supports in special conditions" on railway sections in sandy conditions are considered. Calculations of bearing capacity of the given foundation on the ground on the action of the moment and recommendations on the choice of constructive-technological solutions of erection of the contact network supports on the earthen bed from sandy soils are carried out. The results of analysis and comparison of calculations of bearing capacity of the foundation on the ground on the action of the moment, values of vertical forces acting on the foundation and design bearing capacity of the foundation on the ground by types of foundations of supports are given. The basic requirements for calculation and evaluation of economic efficiency on the use of innovations and achievements of scientific and technical progress in the road sector are outlined. By results of comparison of variants of cost of foundations of supports of a contact network the estimation of economic efficiency of application of new design of foundations of supports of a contact network and increase of their bearing capacity on a ground is made. The application of new design of pile foundations of C-1 (6.5m) and C-2 (9.3m) type in the implementation of projects on electrification of railway sections in sandy conditions is recommended.
