Abstract


This study deals with identifying the behavior of contiguous square footing groups subjected to rainfall water. A variety of parameters were represented in order to study the effect of these parameters on the behavior of the footing group. The tests were conducted in a wide tank with collapsible soil and models of square footing groups. Using the experimental model to investigate the collapse settlement due to the infiltration of rainfall water through collapsible soil beneath contiguous square footing. In addition, the distribution of water content and the depth of wetting were measured. Moreover, numerical models were carried out by PLAXIS 3D V21 to simulate experimental models. From the test results, it was noticed that increasing the number of footings in a group causes a decrease in settlement. 

Keywords


Collapsible soil, collapse settlement, PLAXIS, group of footings, wetted depth, distribution of water content.
