泰州水关遗址是始建于宋代的古砌体城墙遗址,其主结构已严重残损.为了解其结构现状,为保护修缮设计提供科学依据,进行了有限元分析和参数分析.利用有限元分析法分析了4种工况下的裂缝模式、变形和应力;用参数分析法研究了回填土容重、模量等因素对主体结构主拉应力最大值和主压应力最大值的影响.结果表明:对地基最不利的工况组合是自重+回填土压力+附加堆载;对主体结构最不利的工况组合是自重+回填土压力+水压力+附加堆载;主体结构的主拉应力最大值对回填土容重的变化很敏感.
Taizhou Shui Guan Relic Site is an ancient masonry wall ruins built in the Song Dynasty, whose main structure has been severely damaged. In order to understand its structure status and provide a scientific basis for the protection of repair design, finite element analysis and parametric analysis were carried out.Using finite element analysis The crack mode, deformation and stress under four different working conditions were analyzed. The influence of backfill soil bulk density and modulus on the maximum principal tensile stress and the principal compressive stress of the main structure was studied by means of parametric analysis.The results showed that: The most unfavorable condition combination of foundation is self-weight + backfill earth pressure + additional load; the most unfavorable working condition combination of main structure is self-weight + backfill earth pressure + water pressure + additional load; the main tensile stress of main structure Very sensitive to changes in backfill weight.
