利用现有的锚杆承载力计算公式对楠竹加筋复合锚杆和钢筋锚杆的极限承载力进行试算,结果表明,大部分公式对于楠竹加筋复合锚杆的计算结果偏大,而对传统的钢筋锚杆较适用。对以前的研究成果进行了总结,并在对各种土层锚杆承载力计算公式分析的基础上得出了影响锚杆抗拔承载力的因素,提出通过扩大锚杆截面和改良锚固方法可以提高锚杆抗拔承载力的工程建议。
Based on the existing calculation formula of bolt bearing capacity, the ultimate bearing capacity of Nanzhu reinforced composite rock bolt and reinforced rock bolt is tested. The results show that most of the formulas are too large for Nanzhu reinforced composite rock bolt, The more suitable for the traditional steel anchor. The previous research results are summarized. Based on the analysis of the formulas for calculating the bearing capacity of various types of soil anchor, the factors affecting the anti-pull bearing capacity of the anchor are obtained. It is proposed that by expanding the cross-section of the anchor and improving the anchoring method, Engineering Suggestion to Improve Bearing Capacity of Anchor Rods.
