Soil Classification System from Cone Penetration Test Data Applying Distance-Based Machine Learning Algorithms

July 08, 2019
Most work from the literature dedicated to soil classification systems from cone penetration test (CPT) data are based on simple two-dimensional charts. One alternative approach is using machine learning (ML) to produce new soil classification systems or to reproduce existing ones. The available studies within this research field can be considered limited, once ...

Geological-Geotechnical Characterization of Slopes Belonging to the Serra do Mar Paranaense, Brazil

July 08, 2019
An extensive campaign of field and laboratory tests were performed on samples of residual soils and colluviums present in the morphoscultural sub-unit comprising Serra do Mar Paranaense located in Southern Brazil. The geotechnical investigations included the physical characterization, in situ hydraulic conductivity and the mechanical behavior of the soils, by me...

Geotechnical Behavior and Soil-Fiber Interaction of Clayey Soil Mixed with Randomly Dispersed Coconut Fibers

July 08, 2019
This study aims to experimentally analyze the influence of the addition of different amounts of short coconut fibers on the geotechnical properties of tropical clay soil. Samples with 0, 0.5, 1, and 2 wt% of fiber in regard to the dry weight of soil were analyzed. Compaction, direct shear, compressibility, hydraulic conductivity, scanning electron microscopy (SE...

Soil Elastic Modulus Determined by Ultrasound Tests

June 11, 2019

The elastic constants obtained through conventional destructive (triaxial and resilience) tests can present great variability, even for soils with the same classification. Thus, a test is necessary to determine the elastic constants of soils in a reliable and replicable way. The ultrasonic technique is used to characterize rock and several construction ...
