摘　　要：研究目的：在城市中心城区建造隧道，对周围建筑物的影响是个不容忽视的问题，对其进行研究，进而采取有效的措施加以保护，是工程施工顺利进行的有力保证。研究方法：采用数值模拟方法，利用大型有限元软件，通过合理的简化分析和假定建立数值分析模型，分析武汉长江隧道施工对周围历史建筑影响最大的对象——鲁兹故居的影响。研究结论：差异沉降是鲁兹故居应力分布及应力最大值的主要影响因素，差异沉降值的大小对应力分布及应力最大值的大小影响显著，工程中要严格控制地表差异沉降，尽量减小差异沉降值的大小。Research purposes： It is an ignorable problem to make influence on the surrounding buildings by construction of tunnel in the central area in city, so it is necessary to do the research on effective measures for protection of the buildings for guaranteeing the construction going on smoothly. Research methods： The analysis is made for the influence on historical building Luei Former Residence by construction of Wuhan Yangtze Tunnel with numerical value simulation method, large - sized finite - element software and numerical value analysis model. Research conclusions： The differential settlement is the major factor influencing the stress distribution and its max. value on Luci Former Residence, and the value of differential settlement makes big influence on the stress distribution and its max. value, so the differential settlement should be controlled strictly and its value should be reduced as much as possible in construction.
