Research of On-Site Screening and Non-Destructive Testing for Damaged Wooden Components of the Long Corridor in Temple of Heaven

摘要

Take the Long Corridor in Temple of Heaven as an example, some screening and testing process for its wooden components which have damaged was recommended. By pre-knocking survey, the wooden components which probably have damaged were screened out and as the important focus. Then, some non-destructive testing methods such as stress-wave testing and micro-drilling resistance testing were utilized. By the comparison, analysis and interaction correction for the testing images, the internal damaged situation of wooden components were obtained. Three typical types of wooden components were selected in this study, and some specific and suitable non-destructive testing methods which adapt to their position characteristic were discussed. Thus, it can give some useful suggestions and data supporting for the later repairing and management works.
