EXPLORATION AND PRACTICE OF BEIJING BELL AND DRUM TOWERS SAFETY DETECTION PROJECT
Ancient architecture is one of the important historical and cultural heritage content, after many years trials and hardships, there will be a variety of diseases. To better protect the ancient architecture, we need to carry out a detailed investigation to detect and assess its structural safety and stability. Exploration of ancient architecture safety detection, need for an integrated comprehensive and detailed surveying and mapping means drawing detection map, using non-destructive detection techniques to check. We based on three-dimensional laser scanning, integrated utilization technology mapping, ground penetrating radar detection technology, stress wave scanning technology, visual quality and damage prospecting techniques to detect the safety situation in Beijing Bell and Drum Towers. We put forward reasonable suggestions for appropriate repair, on the basis of a variety modal analysis detected the structures, the status of Beijing Bell and Drum Towers safety were assessed. The detection process in this paper has better prospects for the future work that explores cultural heritage of ancient architecture repair detection and appropriate assessment.
