Predicting the Grouting Ability of Sandy Soils by Artificial Neural Networks Based On Experimental Tests

In this paper, the grouting ability of sandy soils is investigated by artificial neural networks based on the results of chemical grout injection tests. In order to evaluate the soil grouting potential, experimental samples were prepared and then injected. The sand samples with three different particle sizes (medium, fine, and silty) and three relative densities (%30, %50, and %90) were injecte...

Strength-Flow Parameters of Loose Silty Sands From Piezocone Tests

Piezocone penetration tests with dissipation phases are particularly useful for geotechnical site characterization. They also provide three independent readings with depth from a single sounding as well as time-rate information. In past investigations, only silty sands with specific silt content have been tested and complete sets of tests have not been conducted to evaluate the influence of dif...

Predicting mindfulness levels according to ego strength

Mindfulness is conscious attention to the current moment and internal/external personal experiences. Researches showed that mindfulness has a relationship with other psychological variables. Ego strength can be defined such as self-control, self-regulation or other relative variables like self-depletion too. The present study examines the predicting role of ego strength on the relationship with...

Numerical Modelling of Dynamic Compaction in Dry Sandy Soils for Determination of Effective Print Spacing

Dynamic compaction (DC) is a widely used soil improvement method in dry and/or saturated soils. The design of DC treatment is usually carried out based on the past experiences and empirical relations. In order to clarify the ambiguities in DC processes, numerical modeling of DC in dry granular soils has been considered using a dynamic finite element code. Using the developed model, two design c...
