摘要：

针对大口径玻璃钢夹砂顶管在施工过程中的受力特点，通过室内试验测试大口径玻璃钢夹砂顶管管材的抗压强度和弹性模量，得到了管材在受压状态下的全过程破坏曲线，进而分析玻璃钢夹砂顶管管材的破坏模式，并对缠绕式和离心浇铸式两种不同加工工艺的材质进行了比较分析．结果表明，玻璃钢夹砂顶管管材属于脆性材料，且两种加工工艺的材质破坏模式不同，离心浇铸式管材的均匀性好于缠绕式管材．

关键词: 玻璃钢夹砂顶管, 管材试验, 抗压强度, 弹性模量, 破坏模式

Abstract:

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 tbe enlaced pipe.

Key words: glass reinforced plastic mortar pipe, materials test, compressive strength, elastic module, failure mode
