摘要
盘式锚杆通过锚盘在土体中发挥作用,很大程度上提高了锚杆的极限拉拔力,表明盘式锚杆在微观锚固机理上有其自身的特殊性。通过MIDAS-GTS数值模拟软件进行建模,分析普通锚杆和盘式锚杆的微观锚固机理,总结出盘式锚杆的特点和优势,更好地指导盘式锚杆在工程实践中的应用。
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 bolt has its particularity in microscopic anchoring mecha nism. 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.
