Development of web application for geotechnical classification of tropical soils based on MCT methodology

Abstract

Geotechnical classifications have the purpose of grouping the soils by their different types, due to their behavior for engineering works. The methodology MCT (Compact Miniature Tropical) was created by Nogami and Villibor to assign appropriate group nomenclatures to the Brazilian soils and to assist in road works, but it’s still less used than others in the professional environment. The main objective of this work was to provide a computational tool that would allow the classification of soils using the MCT methodology through the input data of the Mini-MCV and Loss of Mass by Soaking in Water tests. The applied methodology consisted in the development of a system, employing technologies HTML, CSS, Javascript and the server programming language PHP. As a result, a web application developed based on the client-server model was obtained. This system generates a table with a summary of the parameters obtained and a page containing the calculated coefficients and classification indexes, besides the final classification of the sample. For application’s validation of use, soil samples data tested by Venturini (2015) were used, the results generated were compared with the reference and analytically. Through these results, it was possible to affirm that the classification of soil samples by the MCT systematic using a software was reached and the application developed is able to provide necessary technical assistance for engineering professionals and related, as well as motivate greater employability of the methodology.
