宁波保国寺大殿瓜棱柱内部构造初探

摘要

In this study, the main load-bearing melon-shaped columns of the grand hall of Ningbo Baoguo Temple were examined by nondestructive testing method, and a resistograph was used to probe into the interior structure of these columns based on the resistance curve outline and shape generated by this instrument, combined with different feeding direction of the probe pin. The current study was aimed at providing fundamental data for the renovation and preservation of the grand hall. The results showed that C5, C6, D6, E3, E6, F3, F4, F5, F6 are melon-shaped columns, D4, D5, E4, E5 are jointed melon-shaped columns, C4, D3 are melon-shaped columns with bundles, C3 is special melon-shaped column.%利用无损检测法对宁波保国寺大殿承重的瓜棱柱进行勘查和取样,根据阻力仪曲线的轮廓外形和走势,辅助不同的进针方向,推断瓜棱柱的内部构造,为大殿的保护和修缮提供基础数据支持.结果表明:保国寺大殿中C5,C6,D6,E3,E6,F3,F4,F5,F6为整木柱;D4,D5,E4,E5为瓜棱拼合柱;C4,D3为包镶式瓜棱柱;C3为一特定构造柱.
