Calculation of effective schemes for strengthening shallow foundations by contour reinforcement with hard elements

An effective way to strengthen shallow foundations is contour reinforcement - the execution of vertical elements in soil base along edges foundation. The introduction that perform function a "compression wall" leads noticeable decrease deformations and an increase bearing capacity at reinforced foundations. As reinforcing elements, various structures materials with strength properties exceed corresponding can be used. A positively recommended method for formation group high-pressure injection. essence lies simultaneous supply cement-sand mortar through several sources installed row, under pressure exceeding structural subsequent creation flat injection bodies conditionally rectangular shape soil. important issue determination optimal parameters number spacing plan depth, which lead significant reduction cost work. To determine rational bodies, set numerical experiments was performed calculate stress-strain state foundation different schemes MIDAS GTS NX 2019 software package. calculations were carried out 3D formulation, taking into account nonlinear nature operation. Based on results calculation, most location determined when strengthening technology consistent work gradual substantiated.
