双壁空心柱巷旁充填结构设计与有限元分析

Structural Design and Finite Element Analysis about Double-skin Tubular Columns used in Gob-side Entry Retaining

基于实测研究结果,采用有限元分析软件ABAQUS开展轴向集中荷载作用下钢管混凝土柱的变形破坏特征对比研究。在此基础上提出双壁空心柱沿空留巷巷旁充填结构的设计思想,即采用同心钢管作为充填模板,中空位置充填高水速凝材料。

ABAQUS was used in research to rule in terms of concentrate load compared kind of double-skin tubular columns （DSTC） gain more acknowledge about the deformation mechanic with the test result mentioned in reference. Then,a new consists of an outer tube and inner tube made of steel was proposed, with the space between filled with high water material.
