Factors affecting the efficiency of full-strength tubular pile

The article contains the criteria that give the opportunity to make a quantitative estimates of efficiency optimize a steel tubular pile by materials consumption. The objective of optimize is to reduce the material consumption for the manufacture of pile. On the basis of the studies presented in this article, the following conclusions can be reached. 1) Mathematical model is proposed to ensure the full-strength of pile; 2) Considers the influence of various factors onto the efficiency of the optimize, including: different outside diameters, geotechnical profile, burial depth of pile; 3) There are graphs and tables, which may also be used for approximate estimates of solutions to practical problems
