ABSTRACTThe rehabilitation of old buildings requires detailed knowledge of the mechanical characteristics and stress state of the structural elements, which play an important role in the intervention process. In this sense, non-slightly destructive tests can estimate structural characteristics with good precision at relatively low costs. Consequently, this article presents a device, based on the flat jack technique, applied to continuous stress monitoring over time. It also focuses on the onsite determination of service stresses and its continuous monitoring in several masonry buttresses of a historic building, as well as the assessment of the structural safety before, during, and after an intervention process. A brief analysis of the research is performed, and the motivation and the methodology adopted are described. Finally, the evolution of the measurements recorded and the analysis of the results achieved are detailed. The study enabled recommendations to be made to the intervening agents that guarantee structural safety. 相似文献

半地下砖石建筑遗产在发掘后,温度、含水量等环境条件的波动关联了包括干缩开裂、盐析、微生物生长等在内的诸多病害,使得半地下砖石建筑遗产加速劣化的风险上升,不利于文物价值的有效保护。为明确半地下砖石建筑遗址的依存环境与本体病害特征之间的关联性,本研究以南京上坊孙吴墓为研究对象,进行了现场调研测绘与病害勘察,并对上坊孙吴墓进行了为期一年的室内外环境监测,获取了室外气候、保护大棚内及各墓室内的温湿度等参数,分析了不同病害与依存环境的关联性,并基于环境监测数据评估了墓室内不同区域对应的本体材料劣化风险等级。结果表明,相比于前墓室,覆顶不存的后墓室会表现出更复杂的病害特征,即砖石类遗址在长期的环境波动状态下可能会比在较稳定的高湿环境中面临更高的保存风险。研究结果可为上坊孙吴墓以及同类型半地下砖石建筑遗址保护措施的科学制定提供有价值的参考。 相似文献
