Abstract
A technique is suggested to increase seismic resistance of constructions by using alternative artificial bases. Two types of artificial bases are considered: a (consolidated) soil pad and a pile foundation (with or without pile grating). Criteria have been established for the foundation parameters required depending upon the foundation versus construction stiffness ratio. The construction of a consolidated soil pad 3 m thick (h~3m) with deformation module E0 > 30MPa on soils, which are referred, according to the All-Union Building Standard Specifications (SNIP, 1982), to soil category III, is shown to reduce the level of surface accelerations by a factor of 1.5-2. The thickness of a pad for massive stiff structures has to be minimum and provide the bearing capacity of the foundation. In many cases an artificial base in the form of a pile foundation is desirable. This footing is most efficient in construction on a layer of strongly compressible soil 10-15 m thick overlying solid rock. The effects of such an artificial base on the dynamic characteristics of structures, as well as the properties of pile operation are discussed in the present paper.
