The role of roots in shear strength has been a matter of research and also uncertainties. An investigation was conducted to identify and quantify the contribution of the roots of vetiver grass (Chrysopogon zizanioides) to the shear strength of soils, by means of triaxial testing. Samples were prepared from 4-inch PVC pipe molds, whe...
View ArticleIn this study, fifty driven piles located in the Santos Coastal Plain (“Baixada Santista”), Brazil, have been dynamically tested at various times after installation, indicating gain of capacity over time. The average side shear resistance, related to a low-OCR clayey layer – known as SFL soil, was evaluated over ti...
View ArticleThe sanitary landfill settlement prediction is an important tool for an integrated waste management system once it allows the evaluation of the sanitary landfill useful life and assists in the development of planning actions. Several settlement models have been used as an attempt to estimate the waste volume reduction over time. However, there are few m...
View ArticleIn the design of piles drilled in rock, the following questions arise: (i) at what point of the soil/weathered rock/sound rock profile should the pile socket be designed; (ii) is the contribution of residual soil to be disregarded; (iii)how much consideration should be given to the pile boring method (rotary or hammering). Furthermore, usual design meth...
