Regulation of the Stress-Strain State of Combined Strip Pile Foundation Beds

Quality Estimation of Soil Body during Construction of Foundations with Curved Contact Surface using Harrington’s Desirability Function

“…1 Advanced foundation designs, including those with curved contact surface for Ural and Tyumen oblast, were described in early 1970-s by Tetior [3]. The engineering features were analyzed by numerous researchers, such as Pronozin, Rachkov [4], Poroshin, Epifantseva [5], Ter-Martirosyan, Kiselev [6], Stepanov and Volosyuk [7]. The main engineering difficulty upon erection of such foundations is formation of soil block for reinforced concrete shell.…”

“…Herewith, the erection quality of soil block effects the quality of overall foundation design, its bearing capacity, strength, activation of reinforced concrete shell, foundation settlement. In the case of improper construction of soil base for reinforced concrete shell, the soil body should be additionally pressed [7]. According to procedure of excavation operations during construction of strip shell foundation, it is required to perform mechanical earthworks to the upper level of shell base, mechanical earthworks in trenches for supporting structures, manual formation of soil block aiming at cylindrical concave upward base for reinforced concrete shell of foundation.…”
