【摘要】 钢筋混凝土设缝双肢墩是一种抗推柔度较大的新型桥墩,适用于连续刚构体系。模拟实际工程结构,采用1/10缩尺比例,制作了1个钢筋混凝土整体墩和3个不同填料的设缝双肢墩模型,通过静力荷载试验,研究其在竖向与水平荷载共同作用下的受力机理、应力变形规律、裂缝开展及破坏形态,揭示了各种不同墩的抗推刚度及缝内填料性能的影响。研究结果可为工程实际应用提供理论依据。更多还原

【Abstract】 The reinforced concrete double-limb pier with seam is a new type of bridge pier having a relatively large anti-push flexibility,which is suitable for continuous rigid frame system.The actual engineering structure is simulated by using the 1/10 scale ratio,and makes a reinforced concrete integral pier and three double-limb piers filled with different padding respectively in this paper.The static load test is carried out to study force transfer mechanism,stress deformation law,crack propagation and failure pattern of piers under the action of vertical and horizontal load,meanwhile,also the effects of antipush stiffness for piers with various seam padding are revealed.The research results can provide theoretical basis for practical engineering application.更多还原
