| Title of the article | Experimental researches of deflected mode of double layered soil basis of slab foundation with rigid underlay |
| Abstract. | Popular use of slab foundations in big cities has led to the need of developing foundation slabs’ design procedures, defining safety margins and foundations’ joint deformability with layered ground bases. Experimental studies of slab foundations on layered ground bases were needed to acquire necessary data. Experimental studies of slab foundations layered ground basis’ deflected mode on rigid underlay were conducted. Studies took place in laboratory tray of 1 м3 volume. Double layered ground basis was modeled using clayey soil and sand, slab foundation model’s dimensions are 0.4x0.4m. Layers’ orders and thicknesses varied in studies conducted, while rigid underlay (bass) remained. Foundation model was loaded using hydraulic jack. As a result of experiment, relative deformations of ground massif and settlements of each layer were acquired. Graphs of ground stresses in each layer and on the border of rigid underlay are presented in the article. As a result of experiments conducted, some conclusions, relating necessity of taking in account nonuniformity of ground, compressed in the range of each layer, were made. |
