REFINEMENT OF THE ENGINEERING METHOD USED TO CALCULATE FOUNDATION SETTLEMENTS AND TILTS OF HIGH-RISE BUILDINGS

摘要

A procedure for calculation of bed settlement beneath a slab foundation, which was previously formulated in conformity with schematic representations of regulatory documents and which takes into account the shape of the foundation, the load distribution, and inhomogene-ity of the bed is presented. For simulation of the load on the bed of a high-rise building, a diagram of its deformation beneath the lower surface of a "rigid plate" is proposed. A successive-approximation procedure based on use of equilibrium equations of the slab is developed for calculation of the settlement. Determination of the settlements and tilts of the foundation of a specific high-rise building are discussed as an example.
