The main stages and features of mathematical modeling of the retaining walls and soil foundation interactionin the conditions of a flat problem with the help of LIRA 9.6 software have been described. As a result, the nature of theretaining wall work has been analyzed under various conditions of interaction with the base and with different parameters ofthe retaining wall rigidity. The relationship between the retaining wall rigidity and the resulting equivalent stresses in the soilfoundation under various conditions of interaction has been established. It has been concluded that on the contact surface ofthe retaining wall with a structural surface, the effect of stresses redistribution is achieved and the carrying capacity of thefoundation soil is increased due to the formation of elastic cores and unloading arches.","PeriodicalId":32910,"journal":{"name":"Zbirnik naukovikh prats'' Seriia Galuzeve mashinobuduvannia budivnitstvo","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88410066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
