A case study on the application of the parallel-seismic (PS) and induction-logging (IL) tests combined to evaluate the depth of a 25-cm diameter root-pile belonging to the foundations of a telecommunication tower located in Santana de ParnaÃba, São Paulo, Brazil, is presented. The foundation element is embedded ...
View ArticleCompacted earth embankments are routinely used in dams and many others infrastructure projects in Brazil. It is common to use fine-grained soils for these embankments, which are placed and compacted in the field at specific values of unit weight and water content. Their design is usually performed using geotechnical parameters from laboratory tests on c...
View ArticleBecause of progressively dumping of plastic wastes (PWs) obtained from beverage industry it is of interest to use them as reinforcement material in civil engineering projects. For assessing potential use of plastic wastes in improvement of shear strength of fine-grained soils, two clayey soils were mixed with different amount of plastic wastes (
The supporting mechanism for overburden strata supported by artificial pillars is a complex issue. A calculation method for the size optimization of an artificial pillar in a deep area based on Protodyakonov’s ground pressure theory was proposed. In this study, the sizes of artificial pillars in different mining sections in a specific mine wer...
