Mobile application development for estimation of permissible load on shallow and deep foundation using SPT data

Abstract

The present study demonstrates the development of an Android Application that aims to calculate the allowable bearing pressure for shallow foundations and safe load on pile foundations using the SPT data. The application was built using Android Studio 2020, utilizing XML for the User Interface and Java for the coding. The application offers support for various foundation types, including strip, square, rectangle, and circular shapes for shallow foundations and circular shape for pile foundations. The in-situ SPT data entered by the user was corrected and then processed to calculate soil properties. Subsequently, the bearing pressure for shallow foundation and safe load on the pile was computed adhering to relevant codes. The developed application was verified by comparing the results with already solved examples in the literature. The developed application may be considered under Intelligence in Geotechnics. The created application will be helpful for field engineers to estimate soil parameters and allowable bearing pressure on-site quickly. As a result, it decreases the amount of time and effort necessary for design and thus eliminates the need to refer to tables, codes, and consultants.
