摘　　要：土钉支护是一种用于土体开挖和边坡稳定的新型支挡结构 ,具有良好的延性破坏特征。通过土钉支护在济钢中厚板厂二期工程中的应用实例 ,介绍了土钉支护的局部和整体稳定性计算及工程设计方法 ,并指出土钉支护应注意的问题。The earth nail buttresses are the new soil-catching structure for regolith digging and stability of slope. They have good feature of ductile failure. Taking the application case of the earth nail buttresses in the second stage project of the heavy plate plant of Jigang ,the methods of the sectional and intergal stability calculation and the engineeing design are introduced,and the problems needing attention about earth nail buttnesses are pointed out too.
