煤矸石砼中钢筋粘结锚固的试验研究

Experiment study on bond of anchorage bars in coal gangue concrete

在文献[2]的基础上,对煤矸石砼的粘结应力分布,箍筋及煤矸石砼保护层对粘结应力的影响进行了与普通砼的对比试验.进一步研究砼保护层厚度及钢筋锚固长度对粘结强度的影响,给出了保护层与粘结应力、砼强度与临界锚长的经验公式.

Based on reference[2],the authors compare the distribution of bond stress in coal gangue concrete,and the effects of stirrup and covers on bond strees with common concrete in the tests.This paper further researches the effects of cover thickness and anchorage length of bars on bond strength.The paper puts forward experience formulas of cover thickness and bond strees,that of concrete strength and critical anchorage length.
