Research of perimeter reinforcement of the ground base by cement-sand mortar injection

Abstract

The article analyzes the results of a series of full-scale experiments for studying consolidation of foundations by perimeter reinforcement of the soil by rigid incompressible irregularly shaped inclusions. The experiments modeled consolidation of a shallow soil foundation base by directed high-pressure injection of mobile cement and sand mixtures. Generalization and analysis of the results of several dozens of laboratory experiments allowed to establish approaches to setting rational parameters of perimeter reinforcement of soil foundations by creation of rigid incompressible inclusions using injection of mobile cement-sand mixtures.
