| 摘 要： | 对加固改造工程中钢筋混凝土结构的双筋植筋进行了系统的试验研究,包括不同直径钢筋、不同深度、不同间距对结构锚固性能的影响,得出了一些重要的结论:当植筋深度为15d,且植筋孔净距大于80mm时,可以不考虑单筋锚固强度的折减;当植筋孔净距小于80mm时,需要适当考虑单筋锚固强度约11%~17%的折减。可供加固改造中多筋植筋设计时参考使用。

| Abstract: | The anchorage performance of double adhesive anchors for RC structures in reinforcement and reconstruction engineering is studied systematically by experiments.The effects of various diameter anchors and various depths and various spacing on the anchorage performance are taken into account.Some important conclusions are obtained.The results show that when the anchorage depth is 15d and the net anchorage spacing is greater than 80mm,the anchorage performance is similar to that of the single anchor.When the net anchorage space is less than 80mm,the 11%～17% discount of single anchor′s anchorage performance should be taken into account.The conclusions can provide some references to the design of anchor groups. |
