【摘要】 由于年久失修、自然因素和人为作用等综合原因,武汉市大部分历史建筑存在着不同程度的损伤,有的损坏情况相当严重,也就是说,目前武汉市历史建筑大部分处于需要修缮的阶段,而修缮工作是保护工作的关键所在。国内历史建筑修缮研究刚刚起步,应用也还处于摸索阶段,相应的修缮技术十分缺乏,而历史建筑的损伤检测与诊断工作是修缮工作的前提。本文在武汉市建委科研计划项目(No. 2004-31)的资助下,针对武汉市历史建筑迫切需要解决修缮技术的问题,力求探索出相对简单有效的能够指导武汉市历史建筑健康诊断和修缮的方法和实用技术,因而具有重要的理论与应用价值。论文首先回顾了已有历史建筑的检测及健康诊断技术与方法,并详细讨论了钢筋混凝土历史建筑结构的强度、变形、裂缝、耐久性及整体性能的检测方法和手段,对砖砌体历史建筑的强度、裂缝、及整体性能的检测方法和手段也进行了详细地分析,还详细地论述了历史建筑木构架的检测内容、检测技术、检测仪器及损坏等级的评估划分等。其次,根据课题组对武汉市江汉区30 所保留优秀历史建筑的损坏情况调查,以其中的景明洋行、中央信托局汉口分局、华商总会及大陆坊为典型重点阐述了钢筋混凝土结构及砌体结构历史建筑的损坏情况,根据30 栋建筑的完损情况划分为完好型建筑、基本完好型建筑、一般损坏型建筑、严重损坏型建筑及危房5 个不同等级,对每个等级的建筑提出了总体修缮建议。最后,对武汉市历史建筑的修缮方针与原则进行了探讨,并以30 栋武汉市优秀历史建筑的调查结果为基础,根据不同特点的损坏情况,详细论述了武汉市不同类型历史建筑损坏的修缮工法对策:探讨了用于武汉市钢筋混凝土结构历史建筑修缮的结构杆件修复工法、结构杆件加固工法及结构系统加固工法; 详细论述了针对武汉市历史建筑砖材缺损的灰泥补修工法、单砖替换工法、群砖替换工法及三明治填缝工法; 并对碳纤维复合材料补强武汉市砖砌体历史建筑的对策进行了详细论述; 详细探讨了针对武汉市历史建筑木构件损坏的环氧树脂修缮工法对策。另外本文还以武汉民众乐园大楼的检测和修缮为探讨对象,以前文提出的修缮工法对策为依据,对武汉市历史建筑的检测、修缮进行了典型性探讨。更多还原

【Abstract】 The historical buildings in Wuhan are generally damaged at different states, some of which are damaged seriously due to the long-term use, disasters and artificial actions etc. It is suggested that they should be remedied and preserved urgently. The remedy of these buildings is the pre-requisite work of the preservation project at present, which also poses important challenges due to the lack of corresponding remedial technology in China. Supported by the Research Funds of Wuhan Construction Department (No. 2004-31), the study of this thesis is aimed to find some simple-operated techniques for the remedy projects of the damaged historical buildings in Wuhan, so it is of the high theoretical and applicant value in the field of historical-building remedy. Firstly, this thesis reviews the general methodologies of damage detection and health diagnosis applied to the historical buildings. The detection-techniques and the health-diagnosis methods of the strength, transformation and cracks of RC and brick-wall historical buildings are also discussed in details in this thesis. The detection-techniques for the wooden component of historical buildings are introduced. Subsequently, this thesis describes the damaged-state of 4 case historical-buildings (i.e. Jingming Bank Building, Hankou Office Building of Central Affiance Bureau, Huashang Commercial Building, Dalu Lane) according to the preliminary investigation of 30 typical reserved historical buildings in Wuhan. Here, these four case studies are fully detailed, including the damage and geometric investigations, the analysis of the cause and the justification of remedial schemes for 5 different damaged-state historical buildings. Finally, this thesis is concerned with the remedial principles and methods for repairing and strengthening the historical buildings in Wuhan according to the investigation mentioned above. The structural member repairing methods, the structural member reinforcementing methods and the structural system reinforcementing methods for the RC historical buildings, the lime putty repair method, the single brick replacement method, the multiple bricks replacement method and the putty sandwich method for the brick-wall historical buildings, are described and shown as the measures to remedy the damages. This thesis also discusses the remedial technology using carbon fibre reinforced polymer (CFRP) applied to the brick walls. The epoxide resin remedial methods for the wooden members are also shown in details. In the thesis, a case study is discussed in details, including the detection and remedial measures. Based on the study above, this thesis demonstrates that there are some unreasonable parts in the original remedial scheme and shows the corresponding suggestions for the scheme. The conclusion of these remedial methods can be generalized for most remedial project of historical buildings in Wuhan.更多还原
