大雁塔和法门寺砖材保护研究

大雁塔和法门寺塔这两座佛教名塔都表现出明显的风化现象，需要及时的给于保护。通过X-射线衍射分析、岩相显微镜分析及孔隙度的测定，分析了大雁塔和法门寺两座佛教名塔的风化特征。在此基础上，用几种不同的加固保护剂对两种砖材进行加固保护研究。通过渗透深度、孔隙度、毛细吸水和毛细渗透、持水量、透气性、水力学膨胀、等温吸附、抗压强度及酸腐蚀、冻融、热膨胀之后的强度衰减等参数分析，结果表明含氟聚合物对两种砖材具有良好的加固保护效果。

The deterioration and consolidation of Dayan Pagoda and Famen Temple

The characteristic deterioration mechanism of Dayan Pagoda and Famen Temple were discussed in this paper according to the analysis of minerals by XRD and thin-sectioning. On the basis of these investigations, the penetration depth, porosity, capillarity, water uptake, water vapor diffusion, hygric dilatation, compressive strength and aging-resistance, and so on, were determined before and after treatment with several different consolidates. Fluorinated polymer gave the best results compared with others. The data were confirmed by SEM examination.
