Considerations on Characteristics and Improvements of Soft Soils

This work is aimed at considerations of soft soils, their origin, behavior against applied tensions and the observation of methods that enhance their safety for civil constructions, such as roads, buildings and bridges on this type of soil, making its construction use. Therefore, case studies on soft soils will be presented, in order to understand their mechanical properties and data referring to some techniques that were developed in the study of geotechnical engineering, for the improvement - stabilization - of these soils, such as landfills on: geosynthetics and enriching of soft clays with Deep Soil Mixing (DSM). This article was based on rigorous bibliographic research, including considerations on the attributes, origin and performance of soft soils, generalized display of some improvement methods. Synthetically, a description of two improvement methods was carried out, observing the case studies of both, commenting on how an application of these best cases is made in a legitimate case and in a virtual simulation, with a justification of having an understanding of solutions that uses used, in order that the soft soil masses are useful.
