摘要 通过开展抗压试验,研究UHPC加固低强度砂浆砌体结构受压性能,并根据不同加固厚度、加固层数与拉结方式,确定影响结构受压性能的主要因素。研究结果表明,界面拉结措施对UHPC加固低强度砂浆砌体结构受压承载力、刚度、变形具有显著影响,有效的拉结措施可提高结构受压承载力;在加固层厚度、界面拉结措施相同的情况下,双面加固对砌体结构受压承载力的提高作用优于单面加固。 In this paper, the compressive performance of UHPC reinforced low-strength mortar masonry structures is studied by carrying out compressive tests, and the main factors affecting the compressive performance of the structures are determined according to different reinforcement thickness, number of reinforcement layers and tie methods. The research results show that the interface tie measures have a significant impact on the compressive bearing capacity, stiffness and deformation of UHPC reinforced low-strength mortar masonry structures. Effective tie measures can improve the compressive bearing capacity of masonry structures. In the case of the same interface tie measures, for the reinforcement layer of the same total thickness, the double-sided reinforcement improves the compressive bearing capacity of the masonry structures better than the single-sided reinforcement.
