连续刚构桥竖向预应力损失监测分析

摘要

以某桥梁工程为例，针对该连续刚构桥梁出现腹板开裂的现象进行了分析，通过监测竖向预应力实际锚固损失，并根据相关规范理论进行了计算，为解决预应力箱梁桥腹板开裂问题和竖向预应力设计提供参考依据。%Taking the bridge engineering as an example,the paper analyzes continuous rigid bridge slab cracking phenomenon,monitors actual vertical prestress anchorage loss,carries out calculation according to relevant theories,which has provided some basis for solving prestressed box-girder bridge slab cracking and vertical prestress design.
