Abstract

Underground voids located in the failure zone of the footing can cause serious engineering problem leading to instability of the foundation and severe damage to the superstructure. This paper presents the results of laboratory model tests of the behavior of a strip footing placed adjacent to a sand slope with soft pocket. A comparison between the stress and settlement in the different cases was made to study the most efficient case. The parameters were varied in the study that include the setback distance of the slope crest and the depth of the soft pocket below the footing. Initially the bearing capacity of horizontal cases were determined and then compared with those of footing on sand slopes. The results were then analyzed to study the effect of each parameters. The test results indicated that the existence of such soft pocket within the subgrade layer below the footing has a great effect on the bearing capacity and settlement of strip footing. Also, changing the depth of the soft pocket below the footing was an effect on the stress values. It has been found that the ultimate bearing capacity and the settlement of horizontal ground decreased about 39.8% and 49.1% respectively, compared with the sand slope (b/B =1.0) at Y/B =1.5.
