地铁运营对沿线古建筑的振动影响分析与研究

Vibration Influenced Safety Research on Ancient Architecture along the Line byMetro Operation

以南京地铁3号线运营对南京城墙(玄武湖段)、南京城墙(雨花门段)、中华书局旧址、中南银行南京分行旧址四处古建筑的振动影响为背景,对古建筑进行振动监测,以实测数据为基础,依据现行国家标准规定的振动限值,对地铁运营振动引起古建筑的振动量进行综合评价,从而分析地铁运营振动对该古建筑结构性能的影响大小,为四处古建筑区段的长期保护提供重要参考。

Against the background of the Nanjing Metro Line 3 operations on the vibration of the Nanjing City Wall (Xuanwu Lake Section),the Nanjing City Wall (Yuhuamen Section),the Zhonghua Bookstore Site,and the Zhongnan Bank Nanjing Branch's old site,the vibration monitoring of the ancient buildings was carried out.Based on the measured data and the vibration limit specified by the current national standards, the vibration of the ancient building caused by the subway is comprehensively evaluated.The influence of subway operation vibration on the structural performance of ancient buildings is analyzed,which provides an important reference for the long-term protection of four ancient building sections.
