Grading entropy coordinates and criteria for evaluation of liquefaction potential (2019)
Presentation / Conference Contribution
Barreto Gonzalez, D., Leak, J., Dimitriadi, V., McDougall, J., Imre, E., & Lőrincz, J. (2019, June). Grading entropy coordinates and criteria for evaluation of liquefaction potential. Presented at 7th International Conference on Earthquake Geotechnical Engineering, Rome, Italy

Several methods are commonly used for the evaluation of liquefaction potential in soils. These include criteria based on SPT and CPT tests, shear wave velocity measurements and gradation limits, amongst others. This study applies the concept of gradi...

Grading curves and internal stability (2019)
Presentation / Conference Contribution
Imre, E., Barreto, D., Talata, I., Baille, W., Rahemi, N., Goudarzy, M., Lőrincz, J., & Singh, V. (2019, August). Grading curves and internal stability. Presented at MAFIOK 2019 - Matematikát, Fizikát És Informatikát Oktatók, Dunaújváros, Hungary

The measured grading curve is an empirical distribution function, a step function. This is considered here as a discrete distribution with fixed statistical cells. In the grading entropy theory it is characterized by the... Read More about Grading curves and internal stability.

A note on seismic induced liquefaction (2019)
Presentation / Conference Contribution
Imre, E., Lőrincz, J., Trang, P., Barreto, D., Goudarzy, M., Rahemi, N., Baille, W., Schanz, T., & Singh, V. (2019, September). A note on seismic induced liquefaction. Presented at The XVII European Conference on Soil Mechanics and Geotechnical Engineering, Reykjavik, Iceland

Any particle size distribution can be characterized by two parameter pairs (derived from the statistical entropy formula of discrete distributions) more effectively than simple diameter values (i.e., d50). The first entropy parameter is a conti... Read More about A note on seismic induced liquefaction.

New method for rock qualification (2018)
Presentation / Conference Contribution
János, L., Emőke, I., Phong. Q, T., Miklós, G., László, K., István, T., Barreto Gonzalez, D., Casini, F., & Guida, G. (2018, April). New method for rock qualification. Presented at Mérnökgeológia - Kőzetmechanika 2018 (Engineering Geology and Rock Mechanics Congress 2018)

A new method was elaborated to characterize the breakage properties of rocks. A crushing test was suggested and parallel tests were performed on sand-pairs with different parent rocks, using identical initial gradings. The data were analyse... Read More about New method for rock qualification.
