This article presents the results of studying the influence of the enclosing structure of the pit, made according to the technology of the reinforced concrete wall in the ground of the trench type, on the heeling of a high-rise building on a raft foundation. The study was performed using the numerical method with the PLAXIS 2D software package. The influence of the wall in the ground on the building roll was determined depending on the distance from the wall in the ground to the edge of the raft foundation of the building, the embedding depth of the wall in the ground below the bottom of the excavation and the characteristics of the contact element. The degree of influence of each of these factors on the heeling of the raft foundation was determined by the factor analysis based on the theory of experimental planning. The mosaics of deformations of the soil massif at the base of the raft foundation are given, as well as graphs of the dependence of the change in heeling for the considered factors of influence. According to the study results, the boundaries of the significant influence of each of the factors considered, as well as the walls in the ground as a whole on the heel of the building are determined. The issues are discussed on applications of the study results to reduce the heeling of high-rise buildings at the design stage.
