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。
With the increase of the anchorage length of the anchor rod, the ultimate pull - out resistance of the anchor rod does not increase linearly, but is less and less obvious by gradual increase.
直接拧入式螺杆的极限抗拔力随着拆装次数的增多而下降,但是,当拆装次数为8-9时,极限抗拔力仍然可达到尼龙预埋螺母的水平。
It declines with the increase of times of direct assembling bolt knocked-down. But it can still reach that of nylon inbuilt nut after knocked-down 8 to 9 times.
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.
