损伤空心板梁桥静载试验与分析

对某受损伤的空心板梁桥进行了静载试验,得到桥梁关键截面的挠度、混凝土应变和相关薄弱位置处裂缝变化趋势,结合现场检测情况综合评定桥梁正常使用状况下的承载能力与受力性能的下降幅度,为桥梁的维修加固提供重要的依据。

Static loading test and analysis for cored slab-beam bridge damaged

This article carries on static loading test on cored slab-beam bridge damaged,and obtains changing trend of the critical surface deflection,concrete stress,and crack in relevantly weak position,and comprehensively evaluates the decline rate of bridge bearing capacity and stress performance under normal operation condition by combining with on-spot detection condition,which has provided important basis for bridge maintenance and reinforcement.
