植筋法混凝土与石砌体粘结面剪切性能试验研究

Experimental Study on Shearing Property of Interfacial Bonding of Concrete and Stone Masonry by Planting Reinforced Bar

植筋法被广泛应用于混凝土加固石砌体结构中。采用6个不同参数混凝土和石砌体Z型粘结试件,对有植筋混凝土和石砌体结合面的剪切性能进行试验研究,观测试件的破坏过程并分析其破坏原因,得到各试件结合面的抗剪强度,对不同植筋率和不同植筋深度对结合面抗剪强度的影响规律进行了分析,并对各试件开裂荷载和破坏荷载关系进行了分析。

Planting bar is widely used in concrete to reinforce the stone masonry constructions. Using six different parameters＇ Z bonding specimens of concrete and stone masonry, the experiment of the shear performance of the bonding specimen is conducted. From the experiment, the anti-shear strength of each specimen are obtained, and the failure reasons of specimen are concluded. The adhesive shearing strength behavior of concrete and stone masonry＇ s change regulation under different ratio and different depth of planting steel bar circumstances is studied. And the ductility of the specimens are analyzed.
