Examples of recent designs of retaining walls and their use are given. It is stated thatthe goal is to study the stress-strain state of a retaining wall with a structural surface, considering its contact interaction withthe ground mass. 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":null,"pages":null},"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}

The article suggested a method for conducting a laboratory tray experiment to compare the operationof two models of folded shell foundations. The main stages of conducting the scientific experiment have been describedand the basic principles of selecting materials, devices and equipment for carrying out the experiment have been considered.The conduct of the experiment including data recording for each foundation model has been described. As a result,subsidence data for each foundation model have been obtained. The findings have been analyzed; subsidence graphs for eachfoundation design have been built. It is concluded that better distribution of external load to the foundation system elementsis achieved due to the application of a hinged joint of prismatic folds with supporting beams.
