With the clay ceramsite as aggregate, 52.5 ordinary portland cement as the cementing material, polyester fiber, water-reducing agent and so on, a new kind of metro rail porous sound-absorbing board with cement and ceramsite was produced. The sound-absorbing effects of the tunnel wall and ballast bed of tunnel on different working condition as well as the force performance of the sound-absorbing board in the weak position are studied. The results show that the kind of sound-absorbing board has good sound-absorbing effect and safe structure.
