Abstract
The article identifies the features of the use of composite reinforcement in the pile and strip foundation of a two-story house. When designing the foundations, the complex geological conditions of the construction site were taken into account: a high level of groundwater, their aggressiveness with respect to metal reinforcement (seasonal fluctuation of water supply and water treatment at the time of engineering and geological surveys at a level of 2.8 m); the possibility of landslide processes on the slopes; insufficient knowledge and anisotropy of the properties of the bulk layer, significant thickness of the bulk layer, excluding its removal and replacement. An analytical calculation and a numerical experiment were carried out, the following features of the use of composite reinforcement were established:
 more effective in strip foundations is fiberglass reinforcement, resistant to aggressive influences; ASK is advisable to use only in lightly loaded pile-tape foundations, or with a small pitch of piles due to low rigidity characteristics of ASK. With a significant load on the structures, it is recommended to use combined reinforcement: in areas of pure compression and tension using ASK, and in bending zones - metal reinforcement.

Summary
В статье определены особенности применения композитного армирования в свайно-ленточном фундаменте двухэтажного дома. При проектировании фундаментов были учтены сложные геологические условия площадки строительства: высокий уровень грунтовых вод, их агрессивность по отношению к металлической арматуре (сезонное колебание УГВ, УГВ на момент проведения инженерно-геологических изысканий на уровне 2,8 м); возможность проявления оползневых процессов на склонах; недостаточная изученность и анизотропность свойств насыпного слоя, значительная мощность насыпного слоя, исключающая его вывоз и замену.
