Research on the Damage Mechanism and Site Conservation of the East Gate of Ming City in Lingling
The East Gate of the ancient city of Lingling,which preserves structures from both the Song and Ming dynasties,is a unique example nationwide.The existing East Gate of Ming City exhibits severe deformation and excessive cracking.Despite basic support measures,it is on the verge of failure,with the arch at risk of collapse.Based on historical records and on-site survey data,this study analyzes the damage mechanism of the East Gate.In adherence to the principle of strengthening the protection of ancient sites and preserving historical heritage,the study proposes measures including the removal of parasitic trees and stumps from the protective wall of the arch and the upper rammed earth wall,the installation of new steel structural supports,and penetration grouting for the arch.Using STS/SPASCAD and PMSAP for modeling,computation,and comparative analysis,H-shaped steel(HW150 × 150 × 7 × 10)was identified as the optimal framework for arch support.The study also discusses the installation of the support structure and the restoration of damaged parts of the arch.
