Abstract:

The Taizhou Water Station Site is an ancient masonry structure ruin built in the Southern Song Dynasty. The main structure was severely damaged. In order to understand its current structural properties and provide a scientific basis for protection design, nonlinear finite element analysis and parameter analysis are carried out. The crack patterns, deformations and stresses of the main structure under four load cases are analyzed by nonlinear finite element analysis, and the effect of the backfill bulk density and modulus on the maximum principal tensile stress and maximum compressive stress are studied by parameter analysis. The results show that the most unfavorable condition for the foundation is the combination of weight+backfill soil pressure+additional load; the most unfavorable load case to the main structure is weight+backfill soil pressure+water pressure+additional heap load; the maximum principal tensile stress of the main structure is very sensitive to the changes in the bulk density of the backfill soil.

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.
