潮湿混凝土植筋施工方案对锚固性能的影响

地下工程结构的广泛应用给人们提出了对其进行加固改造技术的新问题。由于地下工程结构所处位置的特殊性，施工工艺对潮湿混凝土的植筋效果有很大的影响。对植筋在荷载作用下的破坏机理和破坏形式进行了论述；对不同施工工艺下潮湿混凝土植筋在荷载作用下的破坏机理和破坏形态作了研究；比较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，潮湿环境下施工工艺对植筋拉拔和锚固性能有较大影响。

Effect of construction scheme for growing bars in damp concrete environment on anchorage performance

With that the underground projects are widely used, a new technical problem of consolidating and reforming them are proposed. As the peculiar place of underground projects, the technology of growing bars affect the effect greatly. This article expounds the damage mechanism and damage shape of the standing loads bars and researches different rules and shapes of damage of different ways in bonding bars; and compares the damp and arid environment standing loads bars accepting force and damage form. The conclusion that the process and method of bonding bars under damp environment has great effect on bonding result is drawn.
