第3节锚杆第24条锚杆的选择必须选择能符合使用目的和用途,而且能满足工程安全和经济性的锚杆。 [解释]在锚杆设计时,选定锚固方式是最重要的因素,但是,很难可靠地推定锚固力。当围岩应力大时,最好在锚杆断裂之前,锚固部分都能起到锚固作用。现在使用的锚杆,根据锚固方式分成端头锚固型、全长粘结型和并用型3种形式。选择锚杆的方法请参考第3编“设计”中第17条。
Section 3 Bolts Article 24 The choice of anchors must be made of anchors that meet the purpose and purpose of use and that are capable of meeting the safety and economy of the project. [Explanation] The choice of anchoring method is the most important factor when designing a bolt, however, it is difficult to reliably predict the anchoring force. When the surrounding rock stress is large, it is best to anchor before the anchor breaks. Now use the anchor, according to the anchoring method is divided into the end anchor type, full-length bond type and the combination of three kinds of forms. Please refer to Part 3 “Design” in Article 17 for the method of selecting anchor.
