Research on the Conservation and Inheritance of theGreat Wall Cultural Heritage Based on Digital Twin |

Abstract: |
The Great Wall cultural heritage has long been exposed
to natural environmental risks such as wind, water, and hail.
Existing research tends to be theoretical, lacking empirical studies
based on digital twin, particularly the simulation prediction of
environmental disasters for the Great Wall cultural heritage.
This paper combines the theoretical model of digital twin with
practical cases to explore the impact of the wind environment on
the Beijing Panlongshan section of the Great Wall through fluidstructure
interaction analysis. It assesses the influence of wind on
architectural structures and investigates the effects of variables such
as vegetation and building volume on the wind environment. The
experimental results demonstrate that digital twin can effectively
predict the risk distribution of heritage under the influence of wind
environments. Moreover, variations in vegetation and building
volume significantly affect wind erosion, and simulation analysis
of localized collapse arches reveals the mechanisms of heritage
damage caused by strong winds and hail disasters. |
