通过土钉抗拔力学模型探讨了高压注浆土钉的抗拔荷载传递机理，简单介绍了其施工工艺。
Based on mechanics model of pullout, the transfer mechanism of pullout load of high-pressure grouting soil nailing is discussed.
本实用新型公开了一种拔钉器，目的是提供一种在拔钉的同时又可清除残钉，结构简单，方便携带和使用的拔钉书钉器。
The utility model discloses a nail puller, which provides a nail puller of simple structure, convenient taken-with and utilization which can pull nail and clean the remained nail.
最后通过试验土钉抗拔力反算土体与锚固体的极限粘结强度，并与规范推荐值进行了比较。
Finally, the limit cohesion strength between the soil and the nail was obtained by in-situ test, and the results were also compared with those regulated by the technical specification.
