【 摘 要 】

The actual issues of expanding the field of application of foundations for high-rise buildings are considered. Traditional foundations are not always effective on construction sites composed of normally and strongly compressible soils; thus, in certain conditions thin-walled strip-shell foundations (TSSF) can be used for cost reduction of the zero cycle. The paper describes the geotechnical monitoring program for GP1.1 built on TSSF - an alternative type of foundation as compared to traditional shallow foundations. The paper presents theoretical modelling of interaction of soil with the building; it also describes the technology of its manufacture using standard materials of STO SRO 001-2015 - "Design requirements for stripshell foundations". The modelling results have shown the efficiency of foundations with a curvilinear convex upwards contact surface. The increased stiffness of the soil bed is caused by additional side squeezing of soil due to the specific features of the contact surface shape. The paper discusses the efficiency of TSSFs as to material consumption and cost as compared to pile-slab foundations. The paper gives the comparative data of geotechnical monitoring and approximate analysis.
