[摘要]我国的城市轨道交通建设日趋成熟,已有大量实例证实,轨道交通的修建和运行会对周边建筑产生影响。选取西安地铁二号线及其沿线重要文物建筑——西安城墙南、北门和钟楼为研究对象,采用数值模拟与现场实测相结合的方法,从文物建筑安全保护方面系统研究地铁盾构施工和运营振动对城墙和钟楼的影响。研究结果表明,城墙和钟楼的变形量在控制范围内。研究成果可为地铁建设中文物保护方案提供科学依据。

Abstract: The construction of urban rail transit in our country is becoming more and more mature, and there are many examples to prove that the construction and operation of rail transportation have impacts on the surrounding buildings. Xi'an Subway Line 2 was selected as the research object as well as important cultural relics buildings along the line including the south gate, north gate and the bell tower of Xi'an city wall. Using the combined method of numerical simulation and field measurement, the influences of subway shield tunnel construction and operation vibration on the walls and bell tower were systematically studied from the perspective of cultural relics building security protection. The research results show that the deformations of the walls and the bell tower are in the control range. The research results can provide scientific basis for the cultural relics protection scheme in subway construction.
 
Keywords: Xi'an subway; shield construction; ground settlement; operation vibration; cultural relics building
