GEOTECHNICAL CALCULATIONS FOR MGE BUROINEKTSIONNYH PILES OF CONDUCT AT STRENGTHENING FOUNDATIONS

Abstract

For a numerical method of boundary elements predicted nesuschayu ability tilted buroinektsionnoy pile length of 14 m, a diameter of 150 mm under the action of both vertical and horizontal loading robot at it at an angle to one another (for gantry scheme) for strengthening the bases and foundations of the gallery. To solve the problem used elastic-plastic dilatancy model ґrunta dispersion medium, which allows you to predict the behavior of buroinektsionnoy piles in the nonlinear stage of its work. A comparison of the results of numerical modeling of the boundary element method with the data of experimental studies, which confirmed a satisfactory correlation.
