ANCHOR PERFORMANCE OF BAMBOO BOLT GROUTED BY PS SOLUTION -BASED SLURRY AMONG RAMMED EARTH MEDIUM
摘要
Abstract
Anchor system of bamboo bolt fully grouted by PS solution-based slurry is successfully applied in the conservation of rammed earth sites.However,the research on its anchoring mechanism has not been conducted so far.By means of the laboratory physical model experiment,anchor capacity,failure mode,strain distribution and load transfer along bolt-grout interface are tested.Experiments reveal that both PS-F and PS-(C+F)anchor system fail at the bolt-grout interface with ultimate pullout force of 1 0~1 5kN and 8~1 6kN respectively.Both of them have strong ductility.During load increment,single-peak and double-peak distributions emerge along bolt-grout interface. Meanwhile,load gradually transfers toward anchor end along with emergence of compressive strain and local peak value near anchor end.All these performance depicts the complicated mechanism.In conclusion,the researched anchor systems are suitable to the conservation of rammed earth sites in terms of anchor capacity.However, durability and structural integrity guarantee of bamboo bolt should be further studied.关键词
