基于ALGOR的桥梁锚固块应力分析及配筋设计研究

Stress Analysis and Reinforcement Design of Bridge Anchor Block Based on ALGOR

文中利用ALGOR的块体应力分析功能,对预应力张拉后灌浆之前的锚固块进行了局部实体单元应力分析,根据锚固块的应力分析结果及分布规律对锚固块的尺寸和配筋率设计进行指导,提出了锚固块设计应注意的区域,以避免锚固块的开裂,增加预应力的有效性。

In this paper,using the block stress analysis function of ALGOR,the solid element stress analysis is carried out for the local anchor block before grouting and after tension of prestressed tendon.According to the stress analysis resultsand distribution law of the anchor block,the size and reinforcement ratio of anchor block is designed.It is a great practical significance to avoid the cracking of anchorage block and increase the effectiveness of prestressing force.
