| 摘 要： | 古建筑墙体尤其是底层墙体常出现粉化脱落现象，通过成因分析，指出墙体粉化脱落属于冻融性破坏，而非腐蚀性破坏。环境温湿度的交替变化、墙体的热湿状况及地下水分的迁移现象是墙体产生粉化脱落的根本原因，根据工程实践，提出防治措施。

| Abstract: | Brick wall of antique building, especially the base wall, usually suffers from efflorescence and falling off. Through analysis on the generation reasons, it is pointed out that efflorescence and falling off of wall belong to freezing-thawing damage rather than corrosive damage. Alternative changes of environmental humidity and temperature, hot and humid conditions of wall and transport phenomenon of groundwater are the main reasons for efflorescence and falling off of brick wall. Therefore, prevention and treatment measures are proposed according to engineering practices. |
