%X A new kind of fully-anchored and multi-wedged slotted tube bolt,alias bamboo-like bolt,is different from currently bolt in functional mechanism and configuration. The bamboo-like bolt is of the characteristics of other full-anchored and end-anchored bolts,and especially the characteristics of multi-anchored bolts. The anchoring force of fully-anchored and multi-wedged slotted tube bolt is comprised of the friction between rock- mass and bolt,bolt end anchorage and multi-wedging force. Testing study is made in laboratory on the anchoring force of the bolt. According to the test result,the average drawing force the bolt is 918. kN and the drawing force of usual slotted tube bolt is only 66 kN,so that the drawing force of the bolt is increased 39%. At the same time,in order to know the working mechanism of the bamboo-like bolts,the RFPA (rock failure process analysis) is used to simulate the shear stress fields of bolt and displacement fields between bolt and rockmass. Moreover the bamboo-like bolts can be installed very simply in rockmass. The results show that fully-anchored and multi-wedged slotted tube bolt is of super mechanical capability and constructional convenience,and can be widely used in supporting and rock engineering.
