摘要
The mechanical behavior of large diameter glass reinforced plastic mortar pipe for pipe-jacking was studied by tests. The compressive strength and elastic module of large diameter glass reinforced plastic mortar pipe material were presented from experiments. The failure mode of the glass reinforced plastic mortar pipe material was analyzed from the stress-strain wreck curves under pressure, and the difference of the failure characteristics between the two types of pipes were discussed. The test results show that the glass reinforced plastic mortar pipe is brittle material, and the failure mode of enlaced pipe and centrifugal pipe is different. The strength and uniformity of the centrifugal pipe is better than that of the enlaced pipe.
