ABSTRACT
At construction sites consisting of medium and strongly deformable soils, traditional foundations are not always effective, and to reduce the zero cycle cost, under certain conditions, Strip-Membrane Foundations (hereinafter—SMF) can be used. SMF consists of a reinforced concrete support contour (strip foundation) and a power membrane made of composite materials, fixed in strip foundations and laid on a natural or artificial base planned along a given curve. To establish the actual interaction patterns of the base and a low-rise building on SMF and compare them with the estimated forecast, it is necessary to conduct geotechnical monitoring during construction and at the beginning of operation. The object of geotechnical monitoring is a three-storey residential building in the town of Novy Urengoy. The article describes the program of geotechnical monitoring of the building constructed on SMF, which is an alternative type in relation to traditional types of shallow foundations. Design modeling of the interaction of the building with the base soil, taking into account permafrost conditions, is presented. The computational modeling data showed the rationality of using foundations with a curved upwardly convex contact surface. The increase in the rigidity of the base soil is due to the additional lateral compression of the soil due to the peculiarities of the shape of the contact surface. The effectiveness of SMF construction concerning consumption of materials and cost in comparison with the slab and pile foundations is presented. The results of comparison of geotechnical monitoring with calculated indicators are given.
