The paper discusses the numerical modelling results of contact layer foundation grill-ground base soil structure damage effect by frost penetration-ground thawing processes.Another part of investigations focuses on contact layer regeneration by crimping for building mechanical safety ensure during the construction and in operation process.Contact layer regeneration is made of cement mortar by injection technology.This method is applicable for construction of combined foundations and deep-grid pile foundations.The paper presents the results of additional ground base deformations and soil structure damage value dependences.The investigations help to establish the crimping organizational and technological parameters,which could include grill-plate in joint work with the ground base more efficiently.Attained results was patented and used in 22-storied buildings construction process in Tyumen,Russia.The geotechnical monitoring confirms the validity of the research.
