摘要
基于摩擦阻荷原理,设计了一种新型平移复位装置,适用于空间狭小的柱墩支撑桥梁结构整体复位,复位过程中桥墩几乎无附加水平力。某曲线连续梁的横向复位实践表明:该复位装置具有良好的实用性,施工便捷,周期短、成本低;梁体旋转复位水平力随位移量逐渐增加,最大旋转复位等效摩阻系数应按照6%进行预估。
Based on the principle of frictional resistance, designed in the present paper is a new type of translation-resetting device, which can be used for the integral relocation of a bridge structure with small clearance on the piers, and in the process of relocation there is little additional horizontal force applied to the piers. The relocation practice of a certain curved continuous bridge shows that the relocation device has good practicability, being simple and convenient in construction, short in the cyclical period and lower in cost. The horizontal force of the rotation and relocation of the bridge body goes up with the increase in displacement, and the coefficient of the maximum equivalent frictional resistance should be estimated at 6%.
