Experimental research of deformed state of uniform soil massif depending on the step of barretts

摘要

Deep foundations are used in the design of high-rise buildings, because it connects with the transfer of large pressure on the soil base. As the foundations of the building sometimes use barretts, which are able to perceive significant vertical and horizontal pressures due to improved lateral surface. Barretts have increased load bearing capacity as compared with large diameter piles. In modern practice, as a rule, the interaction of barretts is investigated by analytical and numerical methods and has no sufficient experimental confirmation. In this article the review of the planned experimental methods of research of the intense deformed state depending on a step of elements in the form of barretts at interaction of model of the soil massif with deep foundation will be made. Experimental research are planned with using of the laboratory stand on the basis of laboratory No 2 of "The bases and foundation on soft soil" for the purpose of obtaining qualitative data on interaction barretts with an assessment of adequacy of settlement model, and also at research of the intense deformed state by numerical methods.
