中文摘要 | 檢測工作是古蹟保存維修之重要工作之一,本研究是利用非破壤試驗法--超音波檢測技術來評價保安宮第一期維修工程中楹的狀況,供作其維修時蟲害防治工程措施與日後定期檢測調查的基礎, 其主要結果如下:1. 超音波檢測技術可應用於古蹟中木構造的調查。2. 較之於傳統使用觀察法與木槌敲打法,超音波檢測能彌補人為檢測上的疏失。3. 所檢測124支楹之超音波傳播速度的分佈,在3894 m/sec以下者佔36.29%,其速度的變異係數一般也較大;反之,傳播速度在3894 m/sec 以上者佔63.71%,其速度的變異係數一般也較小。 4. 造成保安宮木構造部份嚴重的劣化,主要原因為傳統寺廟建築排水不良、保安宮地理位置所造成通風不良、日照不佳、高的溫濕度、蟲害防治不徹底以及未定期追蹤。 |
英文摘要 | Proper investigation is a preliminarily work before conservation and restoration of historic temple. In this study, nondestructive testing method--ultrasonic testing technique-was used to investigate the wood (purlin) properties of Bauan-temple for it's first stage of conservation and restoration. The results provide available informations for the fight against wood-destroying insects and as the groundstone of the investigation work in the future. The main results are: 1. The ultrasonic testing technique showed its feasibility for the evaluation of wooden construction in historic temple. 2. Comparing with the observation method and with the aid of wood hammer, the ultrasonic testing gave no chance of personal ignorance. 3. 36.29% of 124 tested wood samples presented their pulse velocity below 3894 m/sec, most of which had large coefficient of variation. On the contrary, those with the velocity over 3894 m/sec were about 63.71% and their coefficient of variation was small. 4. The most important reasons for the deterioration of wooden construction in Bauan-temple were bad water output system caused by traditional architectural structure of historic temple, lack of wind, lack of sun light, high temperature, high relative humidity, bad job against wood-destroying insects and not being constantly investigated in long term periods. |
