通过开展一维压缩试验，研究2种不同粉碎工艺下获得的粗／细COx土样的压缩特性，结果表明：压缩曲线受粒度成分的影响非常明显，为获得同等压实度，细粒土所需的压实功能较粗粒土高，除此之外，细粒土的压缩指数也高于粗粒土，表现出较强的压缩性；随着土样压实密度的增加，粗／细土样的压缩曲线逐渐靠拢，粒度成分对压实功能影响逐渐减弱；土样卸荷时回弹指数随干密度的增加而增加，受粒度成分的影响不明显；高压实ρ(下标 d=2.0g/立方公分粗粒土样在7 MPa的轴向应力下饱和时，体积发生明显的塌陷现象，饱和后土样的压缩指数小于饱和前，而回弹指数则较饱和前高。

The results show that when the porosity of sample was higher, compressure rate was higher and resilience rate was lower, however resilient rate of sample with higher porosity were increased notably when pressure was increased, and it tended to accord with of sample with lower porosity. The friction coefficient was higher when porosity of paper-based friction material was higher, and the friction coefficient tended to reduce and stabilize when braking pressure was increased. The friction coefficient of sample with high porosity tended to reduce and stabilize in continuous braking cycles.

结果表明：在相同载荷下，随着孔隙率增大，材料的压缩率增加而回弹率降低，随着载荷增加，高孔隙率材料的回弹率先明显增大，而后趋于稳定；在相同比压和转速下，孔隙率越高，材料的摩擦系数越大，随着比压增加，孔隙率高的材料摩擦系数逐渐降低，且不同孔隙率材料的摩擦系数逐渐趋于一致；在连续循环制动时，高孔隙率材料的摩擦系数逐渐降低并趋于稳定。
