摘　　要：古建筑作为重要的物质文化遗产,蕴含着极高的历史、文化和科学价值。在强烈地震或持续交通振动作用下,古建筑可能会发生破坏甚至坍塌。为研究地震和振动对古建筑的影响规律以确保其安全,采用模型试验、数值仿真、理论分析、现场测试等多种手段,开展古建筑抗震和振动控制的相关研究,取得以下主要成果:完善古建筑状态诊断技术,提高检测精度;在揭示古建筑木结构抗震机理及砖石结构地震破坏规律的基础上,提出适宜的古建筑抗震性能提升技术;优化古建筑容许振动标准,建立古建筑振动响应预测方法和多道防线振动控制技术。成果可为古建筑抗震与振动控制保护及其进一步深入研究提供参考。As an important cultural heritage,ancient buildings have high historical,cultural and scientific values.Under a strong earthquake or a continuous traffic vibration,ancient buildings can be damaged or even failed.To study the influences of earthquake and vibration on ancient buildings and hence ensure their safety,physical model tests,numerical simulation,theoretical analysis,and in-situ test are used to develop earthquake resistance and vibration control technologies.The major contributions are as follows.The state-dependent diagnosis technology of ancient building is improved in terms of detection accuracy.Based on the understanding of aseismic and seismic failure mechanisms of timber and masonry structures respectively,the technology is proposed to improve the performance of ancient buildings subjected to earthquake.The permissible vibration of ancient building is elaborated.The prediction method of vibration response and the multi-level vibration control method are established.The results in this study could provide scientific reference for the subsequent explorations on the earthquake resistance and vibration control of ancient buildings.
