| Abstract: | Disc bolts play an anchoring role and improve the ultimate drawing force greatly through the anchor disc used in the soil. This phenomenon shows that disc bolts have its particularity in microscopic anchoring mechanism. This paper makes models and analyses microscopic anchoring mechanism on conventional anchor bolts and disc bolts by numerical simulation software MIDAS-GTS, then sums up the characteristics and advantages of disc bolts, the purpose is to make the application of disc bolts better in engineering practice. |
