木质锚杆加固生土遗址研究

通过对木质锚杆、PS浆液加固生土遗址的现场试验,认为不同的PS灌浆材料对木质锚杆的锚固力的影响不大;木质锚杆、PS系列灌浆材料加固土遗址时锚杆的长度不能太大,长度不宜超过1.5～2.0 m;木质锚杆的单位锚固力可采用5 kN/m,单根锚杆的锚固力大于4 kN;建议可进行木质锚杆、PS系列材料加固土遗址钻孔直径和锚杆长度对锚固力的影响的系统研究,并对锚杆的锚头采用新的方法。

Study on immature earthen sites reinforced with wood anchor

Based on the field test of immature earthen sites reinforced with the wood anchor and PS serosity .The different PS serosity material had little influence to the bolting force of the wood anchor .The length of the anchor was not suitable to be longer than 1.5 m to 2.0 m when the wood anchor and PS serosity were used to reinforce the immature earthen sites. The unit anchoring power of wood could be adopted to equal to 5 kN/m, and the bolting force of the single anchor was larger than 4 kN/ m. It was suggested that the influence of the diameter of drill and the length of the anchor to the bolting force of the wood anchor should be studied and some new method should be adopted to the head of anchor when the wood anchor and PS serosity were used to reinforce the immature earthen sites.
