The effect of contact friction forces on the stress - strain state of an inclined base during the construction of buildings on complex terrain

The paper considers the interaction of contact friction forces in the system "base - inclined foundation - holding structure" and their influence on the stress-strain state of the soil base in the zone of the foundation structure's adjacency to the holding structure. The main features of the contact friction forces' distribution, the places of their application and the calculation algorithm are determined. The design scheme of the inclined foundation is developed taking into account the occurrence of a generalized total friction force. Based on the obtained dependences, the additions and refinements to the existing methodology for calculating foundations on an inclined soil base using a variable stiffness coefficient have been made.
