城市地铁项目建设对古建筑的影响

Influence of Urban Subway Project Construction on Heritage Buildings

为了研究西安地铁二号线工程建设对周围环境产生的影响,并对该工程沿线的古建筑进行保护,通过类比调查和数据分析的方法,分析了西安地铁二号线工程在施工期和营运期对古建筑产生的振动和地基不均匀沉降等影响。结果表明:西安地铁二号线工程建设对地下水的扰动不会影响古建筑的安全;同时,建设产生的振动影响在古建筑的振动允许限值内。为了最大程度地减小西安地铁二号线工程建设对古建筑的影响,提出了合理的古建筑加固方案和工程减振措施。

Aiming at the influence of Xi＇an subway second line construction on surrounding environment, in order to protect the heritage buildings along the engineering project, authors used the analog investigation and data analytical methods to discuss the influence of vibration and foundation differential settlement on heritage buildings during Xi＇an subway second line project construction period and operation period. The result indicates that the perturbation to underground water from this project construction could not affect the security of heritage buildings, and vibration produced by the project construction satisfies the vibration permission limiting value of heritage building. Also, a reasonable heritage building reinforcement plan and engineering anti-vibration measures were proposed, so as to reduce effect of Xi＇an subway second line project construction on heritage buildings to the lowest degree.
