| Popis: | We study the design of drill-injection piles produced by the cup technology with injection of a solution in the mode of formation of "hydraulic fractures" and the formation of controlled broadening at the end of the pile. On the basis of the analysis of the results of laboratory and field tests and the existing methods for the prediction of interaction of the formed body of the pile with soil, we compute the principal design-basis parameters. We propose an algorithm for the evaluation of settlement of the drill-injection pile with controlled broadening taking into account both the variations of the characteristics of the compacted zone of soil near the pile and the influence of residual stresses. |
