Subject: at the present time, the active interaction of various elements of combined piled-raft foundation (CPRF), erected in the conditions of distribution of collapsible soils, has not been sufficiently studied. The subject of the study is technological parameters and design schemes of the combined piled-raft foundation installation. We evaluate the effect of soil compaction of the foundation with ground piles on the formation of stress-strain state of the system (slab-pile-ground base). Research objectives: to reduce the cost and timing of construction of foundations, develop effective design techniques, an assessment was made of the implementation of integrated CPRF technology in the construction of a high-rise building in the conditions of distribution of collapsible soils. Materials and methods: field and laboratory data for determination of physical and mechanical properties of ground soils (humidity, specific and volume weight, humidity at the borderline of rolling and fluidity), grain (granulometric) and micro aggregate composition, swelling and shrinkage characteristics, strength and deformability characteristics (single-plane section, consolidated drained tests), characteristics of subsidence, filtration coefficient; soil testing with static indentation and pull-out loads; computer simulation of stress-strain state of the foundation with the software package Plaxis 2D. Results: field and laboratory experiments resulted in the implementation of integrated technology of construction of the piled-raft foundation on collapsible soil in the conditions of dense urban development. Conclusions: the proposed design method of the piled-raft foundation has allowed us to improve construction properties of soil, considerably increase the pile bearing capacity, reduce depth of piling and effectively include the ground-soil of a longitudinal part of the foundation into work. This method gives considerable economic effect and reduces the construction duration.
