Aiming at the support problem of large deformation of surrounding rock in deep high ground stress roadway, a kind of compressible concrete-filled steel tube support structure (referred to as "compressible support") was proposed. Firstly, a comparison test of compressible similar materials was carried out, and PVC foam was determined to be applicable as the compressible similar material for simulation tests. Secondly, the similar simulation test of the compressible support was carried out, and the stress-time and load-displacement curves of the whole process of static load were obtained. The evolution of compressible support, initiation and propagation of concrete cracks was monitored. Three mechanical response stages of the compressible support were revealed: the elastic deformation stage, stable yielding stage and rigid stage after yielding. The test results show that the peak stress of the surrounding rock of the roof and floor is approximately 0.7 MPa, and the peak stress of the surrounding rock of the left and right sides is approximately 1.4 MPa. The stress of the surrounding rock is transferred to the depth, the supporting model does not experience overall instability and deformation, and the support is bent, but the structure is still intact. The compressibility of PVC foam measured is approximately 77%, indicating that the support achieves a favorable yielding effect. The field application results show that the maximum displacement of the roof and floor of the surrounding rock is 216 mm, and the compressibility of the compressible support is about 72%. The compressible support achieves favorable supporting performance, and the support structure can effectively coordinate the collaborative deformation of the surrounding rock and support. The research results can provide reference for the support design and engineering application of the compressible support.

针对深部高地应力巷道围岩大变形的支护难题，提出了一种可缩式钢管混凝土支架支护结构（简称“可缩支架”）。首先开展了可缩相似材料的比选试验，确定了PVC泡沫可用作模拟试验的可缩相似材料。然后开展了可缩支架相似模拟试验，获得了静载全过程的应力-时间、载荷-位移曲线，监测到支架可缩、混凝土裂缝产生与扩展的变化状态，揭示了可缩支架的3个力学响应阶段：弹性变形阶段、稳定让压阶段和让压后刚性阶段。试验结果表明：顶底板围岩应力峰值约为0.7 MPa，左右帮围岩应力峰值约为1.4 MPa，围岩应力向深处传递，支护模型整体未发生失稳变形，支架出现弯折，但仍保持结构完整；PVC泡沫可缩率约为77%，支架让压效果良好。现场应用结果表明：围岩顶底板最大移近量为216 mm，可缩支架可缩率约为72%，可缩支架的支护效果良好，该支护结构能有效协调围岩-支护协同变形。研究结果可为可缩式支架的支护设计及工程应用提供参考。
