Computer Modeling of Temperature Fields in the Soil and the Bearing Capacity of Pile Foundations of Buildings on Permafrost

Year: 2024

Abstract: Global climate warming challenges the permafrost areas losing the frozen state and stabil- \nity. Industrial development and human activity in these regions also contributes to the degradation of \npermafrost. The construction of residential buildings and their operation in these territories mainly in- \nvolves maintaining the soil under these structures in a frozen state throughout the entire period of their \noperation. For these purposes, pile foundations and ventilated crawl spaces are used. The basements \nmay also include the devices aiding stabilize the soil. For example, it could be hundreds of the seasonally \noperating cooling devices. An urgent task is long-term forecasting of the dynamics of changes in the \nbearing capacity of a pile foundation of a building, considering climatic and technogenic impacts on \nthe surrounding soil. A new model and numerical algorithm were developed to study the dynamics of \nchanges in the bearing capacity of piles during the operation of the building, considering temperature \nmonitoring data from temperature sensors located in thermometric wells. Validation of the developed \nsoftware package was carried out based on the existing and constantly arriving data on soil temperature \nmonitoring to a depth of 10 meters on the server. A comparison of the obtained monitoring data and \nthe calculated data in thermometric wells showed a significant improvement compared to the previously \nused model and calculation program for this residential building
