Application of a sensitivity analysis procedure to interpret uniaxial compressi...

Jet Grouting (JG) technology, one of the most efficient soft soils improvement methods, has been widely applied in important geotechnical works due to its versatility. However, there is still an important limitation to overcome related with the absence of rational approaches for its design. In the present work, three different Data Mining (DM) techniques, i.e., Artificial Neuronal Networks (ANN), Support Vector...

Previsão do comportamento mecânico de formulações laboratoriais de solo-cimento...

Atualmente, no âmbito dos métodos de tratamentos de solos, o jet grouting (JG) é uma das tecnologias mais utilizadas, nomeadamente em importantes obras geotécnicas, caracterizando-se pela sua grande versatilidade. No entanto, no que respeita à previsão das propriedades mecânicas do novo material resultante do tratamento, a heterogeneidade dos solos e o elevado número de parâmetros envolvidos são os fatores que ...

Application of data mining techniques to jet grouting columns design

Tese de doutoramento em Civil Engineering (ramo de conhecimento em Geotechnics) ; Jet Grouting (JG) is actually a reference method on soil improvement technologies, allowing to improve the strength, stiffness and permeability of soft soils. However, even after several years of practice and notable technology advances, there are still some limitations to overcome. In particular, the main limitation is the abse...

Application of data mining techniques in the estimation of the uniaxial compres...

Jet grouting (JG) is a soil treatment technique which is the best solution for several soil improvement problems. However, JG lacks design rules and quality controls. As a result, the main JG works are planned from empirical rules that are too conservative. The development of rational models to simulate the effects of the different parameters involved in the JG process is of primary importance in order to satis...

Strength and stiffness are the mechanical properties currently used in geotechnical works design, namely in jet grouting (JG) treatments. However, when working with this soil improvement technology, due to its inherent geological complexity and high number of variables involved, such design is a hard, perhaps very hard task. To help in such task, support vector machine (SVM), which is a data mining algorithm es...

Uniaxial compressive strength prediction of jet grouting columns using support ...

Uniaxial compressive strength (UCS) is the mechanical properties currently used in geotechnical works design, namely in jet grouting (JG) treatments. However, when working with this soil improvement technology, due to its inherent geological complexity and high number of variables involved, such design is a hard, perhaps very hard task. To help in such task, a support vector machine (SVM), which is a data minin...

Sometimes, the soil foundation is inadequate for constructions purpose (soft-soils). In these cases there is need to improve its mechanical and physical properties. For this purpose, there are several geotechnical techniques where Jet Grouting (JG) is highlighted. In many geotechnical structures, advance design in- corporates the ultimate limit state (ULS) and the serviceability limit state (SLS) design criteri...

A data mining approach for jet grouting uniaxial compressive strength prediction

Jet Grouting (JG) is a Geotechnical Engineering technique that is characterized by a great versatility, being the best solution for several soil treatment improvement problems. However, JG lacks design rules and quality control. As the result, the main JG works are planned from empirical rules that are often too conservative.
