中国古代砖砌体力学性能研究综述

古代砖砌体建筑由于材料劣化、环境影响,材料特性及力学性能均受到不同程度的影响和损伤,为了保护历史文化的载体,结合古建筑材料获取原始且必要的数据,系统总结了古砖、传统灰浆的制备工艺和材料性能,简要归纳了古砖、传统灰浆和古砖砌体基本力学性能及其测试方法,对比分析了单砖和砌体抗压强度的差异以及古建筑砌体材料力学性能研究现状。并对今后古砌体如弹性模量等力学性能、古砌体材料及结构的损伤机理等的研究提出了展望或建议,可为砖石古建筑的修缮保护提供参考依据。

Research on the basic mechanical properties of ancient Chinese brick masonry materials

Due to material degradation and environmental impacts, the materials and mechanical properties of ancient brick masonry buildings are affected and damaged to varying degrees. In order to protect this carrier of history and culture, combining raw and necessary data obtained from ancient building materials, we systematically summarized the process of preparation and the material properties of ancient brick and traditional mortar. The basic mechanical properties and test methods of ancient brick, traditional mortar and ancient brick masonry were briefly summarized. The differences in compressive strength of single brick and masonry and the research status of mechanical properties of ancient building masonry materials were compared and analyzed. Future research on the mechanical properties of ancient masonry, such as elastic modulus and damage mechanisms of ancient masonry materials and structures is suggested. This work can provide reference for the repair and protection of ancient masonry buildings.
