以虎门炮台旧址范围内文物影响评估为工程背景，在公路交通规划阶段对古建文物防振安全性进行全过程性能化分析、实测与防护措施研究。通过现场重载车辆行驶场地及古建筑文物振动实测，得有限元分析关键技术参数，对包括“车辆、道路、场地、文物”的有限元模型进行校准；采用校准后有限元模型对车辆轴重、行车速度、多车效应、隔振沟尺寸等参数分析研究，得文物的振动响应；用性能化指标评价文物振动安全性，采取合适振动防护措施。实测与分析表明，实测与分析结合全过程性能化分析法能用于交通规划文物保护研究，公路50 m辅以隔振沟可保证古建筑文物的振动安全性。

Under the background of Heritage Impact Assessment project in the region of Humen Fort related areas, the whole process performance-based analysis integrated with measurements and anti-vibration measures for the vibration safety of ancient structures in road planning stage was carried out.The vibration of the related soil layers and ancient structure under heavy vehicles excitation was measured,and the key technical parameters of a finite element model (FEM)including“vehicle,road structure,related site’s soil layers and ancient structure”were calibrated according to the measurement results.And then,the influences of the vehicle axle load,vehicle speed,multi-vehicle effect and isolation trench dimensions were analysed by using the calibrated FEM,and the vibration response of ancient structure was obtained.The performance-based indexes were accepted to evaluate the vibration safety of ancient structure,and the reasonable anti-vibration measures were proposed according to the finite element analysis results.The measurement and analysis show that,the proposed whole process performance-based analysis combined with corresponding measurements can be used for transportation planning and relics conservation.The vibration safety of ancient structure can be guaranteed when it is spaced 50m apart from the road.
