潮湿混凝土种植钢筋锚固性能的试验研究

The eperiment research of anchoring performance about growing bars in damp beton

混凝土的植筋在结构加固和改造方面得到越来越广泛的应用,但在地下工程潮湿环境下混凝土植筋的施工质量控制是有待进一步研究的问题。本文对不同施工方案下混凝土植筋试件进行了拉拔试验,对比了潮湿和干燥环境下混凝土植筋在荷载作用下的受力和破坏形态。结果表明,潮湿环境下清孔工艺对植筋锚固性能有较大影响。

Reinforced bars are widely used in structure consolidating and reforming. Yet, the process and method of bonding bars of damp environment has great effects on the bonding result, but which is seldom researched. This article analyzed the damage mechanism and damage shape of the standing loads bars which under the damp environment, researched different rules and shape of damage of different ways in bonding bars. Compared the damp and arid environment standing loads bars accepting force and damage form. Drawing conclusion：the process and method of bonding bars under damp environment has great effect on bonding result.
