摘要
该文结合重庆某边坡工程,对中风化砂质泥岩与锚固体粘结强度进行了试验研究。根据工程实际情况,共设置6根锚索进行基本试验。结果表明:(1)锚索的主要破坏形式为位移不收敛,锚固体从岩层中拔出;(2)中风化砂质泥岩与锚固体粘结强度标准值为700kPa。可为同类工程锚索设计提供参考。
Based on a slope project in Chongqing,a test research was conducted on the bonding strength of moderately weathered sandy mudstone with anchorage bodies.According to the reality of the project,a total of 6 anchor cables were set for the fundamental test.The results showed that:(1)The main failure mode of anchor cables displays the converge displacement and the pulling out of anchorage bodies from the mudstone;(2)The standard value of the bonding strength of the moderately weathered sandy mudstone with anchorage bodies is 700kPa.It can provide a reference for the design of anchor cables for similar projects.
