Toughening column type pier bridge anti-overturning structure
The invention relates to the technical field of civil engineering, in particular to a toughening column type pier bridge anti-overturning structure which comprises a steel structure which is connected to the position, close to a beam body, of the upper portion of a pier through high-strength anchor bolts and used for achieving transverse pier expansion connection, and steel fiber concrete is poured into the space between the steel structure and the high-strength anchor bolts; the transverse prestressed tendons are arranged at the positions, close to the beam body, of the upper portions of the bridge piers, support the steel structures and apply transverse precompression to the bridge piers and connecting structures of the bridge piers, so that the original upper cross sections of the bridge piers are in vertical and transverse compression states; the vertical supports are arranged on the two transverse sides of the steel structure and located at the positions, close to the main beam, of the upper portions of the bridge piers, and gaps are reserved between the top faces of the vertical supports and the bottom face of the beam body, and the vertical supports have the advantages that under the condition that the requirement for slight deformation of the bridge under the normal running state of vehicles is met, the overall anti-overturning capacity of the bridge is improved, and meanwhile early warning can be conducted on the limit state.
本发明涉及土木工程技术领域,具体来说是一种增韧柱式墩桥梁抗倾覆结构,包括钢结构,通过高强锚栓连接在桥墩上部靠近梁体的位置,用于实现横向桥墩扩大连接,并在钢结构和高强锚栓之间的空间内灌注钢纤维混凝土;横向预应力筋,设置在桥墩上部靠近梁体的位置,且支撑所述钢结构,对桥墩及其连接构造施加横向预压力,使桥墩原有上部截面处于竖向和横向受压状态;竖向支撑,设置在钢结构横向两侧,且位于桥墩上部靠近主梁的位置,竖向支撑的顶面与梁体底面之间留有间距,其优点在于:在保证车辆正常行驶状态下桥梁轻微形变的要求下,提升了桥梁整体的抗倾覆能力,同时能够对极限状态进行预警。
