Abstract:

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.

Key words: nondestructive testing, melon-shaped column, resistance curve, interior structure
