中文摘要	某国家级文物古建城台外砌砖砌体出现了许多裂缝,需确定其产生原因及其对城台安全性的影响。本文借助大型通用有限元软件MARC建立城台的弹塑性接触有限元模型,通过计算分析外砌砖砌体裂缝产生的主要原因,探讨了外砌砖砌体的裂缝分布和侧向变形与其受力性能恶化间的内在关系。结果表明,城台外砌砖砌体的裂缝及侧向变形是其受力性能恶化的直接表现,通过对外砌砖砌体的裂缝分布和侧向变形监测可判定城台的安全状态。; Many cracks have appeared in the external brick masonry of a national relic ancient platform.The masonry cracking cause and the influence on the safety of the platform should be determined.Elastic-plastic contact finite element model for the platform was established by applying large general software MARC,the main cause of cracking and lateral deformation in the masonry was analyzed by means of calculation,and the internal relationship between crack distribution and lateral deformation in the masonry and its mechanical property deterioration were investigated.The results show that cracks and lateral deformation of the external brick masonry of the platform are direct embodiments of the masonry mechanical property deterioration,and the safety state of the platform can be estimated by monitoring the distribution of the masonry cracks and its lateral deformation.
