应用岩土分析软件对竖直抗拔的扩体锚杆进行了数值分析，得到扩体锚杆锚周土的应力变化情况，分析结果表明：随加载力的增大，扩大头部分破坏体范围不断扩大，达到极限承载力后，破坏范围呈帽状且不再扩大。
應用巖土分析軟件對豎直抗拔的擴體錨桿進行瞭數值分析，得到擴體錨桿錨週土的應力變化情況，分析結果錶明：隨加載力的增大，擴大頭部分破壞體範圍不斷擴大，達到極限承載力後，破壞範圍呈帽狀且不再擴大。

Geotechnical analysis software was used to analyze the underreamed ground anchors,and the stress distribution of soil around anchor was obtained. The results show that the damage scope enlarged along with the increase of loading,and after reaching the ultimate load,the shape of damage was similar to the outline of cap.
