Annotation: In the article the research results of constructive methods of buildings and structures protection resulted from karst displays. The method of calculation is offered and the tensile-deformed state of constructive elements of building has been proposed. As measures on protecting of buildings and structures from karst displays are foundations of continuous slab and cross beams kind have been offered. By means of program complex LYRE calculation efforts and moving of the protected constructions of buildings and structures have been determined, getting in to the karst gap zone. The karst funnel of 3, 6 and 9 m diameter was investigated. The funnel disposition under foundations has been considered in the places of axes crossing under columns, in the corner of the building, in the center of the greater side of the investigated building and in the central part of building. It has been determined that the most unfavourable influence of karst gap is in the central part of building. The technical and economic comparison of investigated constructive measures is offered. While protecting of framework few storey building from the karst influence by means of foundations setting as cross beams is more economical in comparison with this building protection by foundations arrangement as the continuous slab.
