| 摘 要： | 采用应力波测定仪对西藏古建筑上的腐朽与虫蛀木构件进行无损检测和目测腐朽观察,并将两种结果进行比较.结果表明:应力波无损检测技术可以准确的判定木构件的内部腐朽与虫蛀;表层腐朽分级与无损检测结果基本一致;在古建筑维护中,可在目测基础上,再采用应力波技术检测确认,为准确更换木构件提供定量评价依据.

| Abstract: | Decayed and insect attacked ancient poplar and larch wood components from the buildings of Tibet were inspected by a stress wave meter(FAKOPP).The decay in each wood component was observed and classified after having been measured by FAKOPP.The comparison between the stress wave evaluation and visual classification showed that internal wood decay and insect infestation on ancient wood components could be detected accurately by stress wave.The decay situation evaluated by stress wave was almost consistent with the visual classification.Based on the results,the authors determined that visual observation combined with stress wave methods could examine the degradation of wood members in ancient buildings. |
