With the increase of the anchorage length of the anchor rod, the ultimate pull - outresistance of the anchor rod does not increase linearly, but is less and less obvious by gradual increase.
锚杆随着锚固长度的增加，极限抗拔力并不是线性增加的，而是增加得越来越不明显。

The tests of bonding power between polystyrene board and concrete, plastic expanded tube pull- out, compressibility, freeze resistance show the system property is reliable and high safe.
经聚苯板与混凝土粘合力、塑料胀管抗拔力、压缩率及抗冻试验表明该体系性能可靠、安全度高；

Again, we're talking about that long line, the least amount of resistance is going to get you further on every pull-out.
