为适应连续刚构桥在次中跨合拢前后的刚度变化及改善矮主墩的受力 ,在对边主墩施加水平推力的前提下实现了合拢 ,为矮墩连续刚构体系的施工提供了新的思路
In order to meet the rigidity change of continuous rigid-frame bridge before and after the secondary mid-span confluence and to improve the force of short main piers, under the precondition of exerting horizontal thrust to the side main piers, the closing is achieved and the construction of short rigid piers continuous rigid-frame system is provided New ideas
