摘　　要：乐安流坑古村怀德堂照壁墙艺术人文价值闻名于世,对怀德堂照壁墙的现状稳定性分析评价是制定中长期加固保护方案亟待解决的问题。通过构建了屋盖系统、梁、柱及照壁墙等整体结构数值仿真模型,反演分析再现了怀德堂照壁墙的现状病害特征,得出表征照壁墙现状的墙体材料特性参数,对照壁墙在不同程度劣化状态下塑形破坏区发展、墙体变形趋势及整体稳定性进行了评价。结果表明,怀德堂照壁墙现存状态下整体稳定性良好,但随着青砖材料劣化、墙体变形趋势不断发展,照壁墙会因墙砖雕饰面砌块相互挤压、剥离、错动而造成墙壁破损、丧失艺术文化价值。研究成果为怀德堂照壁墙加固保护方案的制定提供了支撑和依据。Huaide Hall in Liukeng ancient village in Le’an,is famous for its screen wall with artistic and humanistic value.The stability analysis and evaluation of the screen wall of Huaide Hall is a problem to be solved in formulating a medium and long-term reinforcement and protection scheme.The numerical simulation model of the whole structure including the roof system,beams,columns,and screen wall is constructed.Through the inverse analysis,the current disease characteristics of the screen wall of Huaide Hall are reproduced,and the material characteristic parameters that can characterize the current situation of the screen wall are obtained.The development of the plastic failure zone,the deformation trend,and the overall stability of the screen wall under the different degrees of deterioration are evaluated.The results show that the overall stability of the screen wall of Huaide hall is good in the existing state,but with the deterioration of the brick wall materials and the continuous development of wall deformation trend,the brick carving finish blocks of the screen wall will squeeze,peel and stagger each other,and lose their artistic and cultural value.The research results provide support and a basis for the formulation of the reinforcement and protection scheme of the lighting wall of Huaide Hall.
