摘　　要：锚杆作为支护体系的主要承载体在支护领域中发挥着不可替代的作用。为适应愈加复杂的工程条件,新型锚杆不断涌现。笔者从新型多节式预应力锚杆的发展历程、工艺特点等方面,通过对比普通机械涨壳式锚杆存在的不足,详细阐述了新型多节式预应力锚杆的优势及其实施方法,对实际工程应用具有指导意义。As the main bearer of the anchor-plate retaining system,anchors play an irreplaceable role in the field of anchor supporting.To fulfill the increasingly complex engineering conditions,new types of anchors have been springing up. By comparing the general machinery shell of the defects in the bolt,this study elaborates the advantages of the new multi-prestressed anchor and its implementation method from its operation; it also analyzes the technological features of prestressed anchors which offer valuable reference for practical engineering applications.
