摘要

目的:这项工作的目的是确定在不稳定土壤上天然石材基础发生重大运动时建筑物墙壁和柱子的承载能力。方法:采用Ing+2021 MicroFe软件包建立应力-应变状态有限元模型。研究发现:在1854年以来168年的长期服务中,土壤冻融、碎石基础冻胀和汤姆河的岩土工程影响造成了低潮期和汛期水位的显著波动。地基相当沉降,破坏了这座历史建筑的空间刚性。实际意义:获得的结果可用于制定建议,通过在楼板间和阁楼天花板上用张拉钢带加固外墙,确保砖砌建筑的必要空间刚度。

The influence of nonuniform movement of rubble foundation on bearing capacity of brick walls of a historic building
Purpose: The aim of the work is to determine the bearing capacity of walls and columns of the building during significant movement of its natural-stone foundation on unstable soil.Methodology: The finite-element model of stress-strain state is developed by using Ing+2021 MicroFe software package.Research findings: During 168 years of the long-term service since 1854, the negative effect from soil frost-thawing, frost heave of the rubble foundation, and geotechnical influence of the Tom river, provided a significant fluctuation of the water level during low-water and flood periods. The foundation was considerably settled, that disturbed the spatial rigidity of the historic building.Practical implications: The obtained results can be used to develop recommendations for ensuring necessary spatial rigidity of the brick building via the reinforcement of exterior walls with tensioned steel ties on inter-floor and attic ceilings.
