摘要
针对目前我国预应力混凝土锚下开裂现象,在对国内外预应力混凝土锚固区设计规范进行对比分析的基础上,以具体试验为例,分别采用不同规范进行了锚下极限承载力计算,并进行对比统计分析,得到了一些有意义的结论。
Aiming at the phenomenon that cracks emerge under the anchor of the pre-stressed concrete in present China,on the basis of the comparison and analysis on design regulations of anchorage zone of pre-stressed concrete in home and abroad,with specific trials as examples,the thesis separately adopted different regulations to calculate the ultimate bearing capacity of the anchor,and comparison,statistics and analysis were done,and got some meaningful conclusions.
