摘要：
The load bearing behaviour of fully grouted fiber reinforced polyester and epoxy rock anchors under shock loading was investigated using a special facility for dynamic tests. Two concrete blocks were connected with the anchor. With a constant acceleration three loading blocks with different weights were used to produce various dynamic forces on the anchor and the grout material. Of special interest were the length of exceeded bond strength in the grout material and the load capacity of the fiber reinforced anchors. The residual resistance of the anchors was tested by push-out tests of specimens to estimate the loss of bond strength and its distribution over the anchor length. The results refer to a realistic scale.
