历史建筑中湿度上升会导致材料劣化、能源浪费、与水有关的损坏、室内空气不舒适和霉菌滋生。实际墙体的上浮过程受建筑类型、砌块细部、环境条件、砖和砂浆物理性能等因素的影响。为弄清蓝砖砌体墙结构型式对墙体增湿的影响特征，在密闭的实验室内建造了高3米(高)×1.2米(宽)×0.24米(厚)的粘土蓝砖和石灰砂浆砌成的实心墙和空心墙，进行了600天的升水试验。结果表明，结构形式直接影响尖锋上升速度和尖锋高度，600天后洞壁上升速度为192 cm，实心壁上升速度为168 cm。实心壁和空心壁中水分上升的计算模型服从均质壁的尖锋模型，但环境条件影响着尖锋的上升和水分的分布。该研究拓展了对实际砖混结构中湿度上升现象的认识，并为砖混结构的湿度模拟、能耗和遗产保护提供了数据支持。
The occurrence of rising damp in historical buildings results in material deterioration, energy waste, water-related damage, uncomfortable indoor air, and mould growth. The rising process in a real wall is influenced by the construction types, masonry details, environmental conditions, physical properties of brick and mortar. To clarify the features of rising damp influenced by the construction types in blue-brick masonry walls, a solid wall and a cavity wall made of clay blue bricks and lime mortar with a size of 3 m (high) × 1.2 m (wide) × 0.24 m (thick) were constructed to perform a water rising experiment for 600 days in a closed laboratory. The results demonstrated that the construction types directly affected the rising speed and the height of sharp fronts, which were 192 cm in the cavity wall and 168 cm in the solid wall after 600 days. The calculation model of the moisture rising in the solid wall and cavity wall obeyed the sharp front model of a homogeneous wall; however, the environmental conditions affect the rise of sharp front and moisture distribution. The research expands the understanding of the rising damp in real masonry and provides data supporting the moisture simulation, energy consumption, and heritage conservation of brick masonry.
