| 摘 要： | 预应力锚杆支护在实际工程中应用很广，但缺乏相应的理论及试验研究。给出了预应力自由式锚杆及全长粘接式锚杆在不同墙面上受力的不同的预应力值大小对支护效果影响的对比试验。试验表明，两者初始破坏荷载相同，但整体失稳荷载存在差异。

| Abstract: | Prestressed anchor member support is widely used during engineering, but the relevant theory and test research are insufficient. This paper presents comparative tests of the different stress conditions of prestressed anchor member with free way and cohesion way in the whole length given to the effect of support in different wall. The test results suggest that both loading of initial breach are the same but different in integral unsteadiness loading. |
