Avaliação da capacidade de carga de terreno de fundação formado por camadas de blocos de rocha compactados

Assessment of the load-bearing capacity of foundation soil composed of layers of compacted rock blocks

Abstract

This article presents an evaluation of the load-bearing capacity of a layer of compacted rock blocks, using shear strength parameters obtained through the GSI geomechanical classification system. This approach allows for estimating the load-bearing capacity of the soil-foundation system by applying established theoretical methods. The behavior of the rock material was assessed through a plate load test, and the results indicated that the assumption of treating the compacted rock block layer as a rock mass yielded a load-bearing capacity consistent with that determined from the plate load test. Furthermore, the geotechnical parameters derived from the back-analysis of field test results aligned well with those obtained via the application of the GSI system. Therefore, utilizing geomechanical classification systems is shown to be a viable methodology for designing shallow foundations on layers of rock blocks
