A support structure, including an excavation and a plurality of irregularly shaped foamed glass bodies at least partially filing the excavation. Each respective irregularly shaped foamed glass body has an aspect ratio of about 1:1.7 and a diameter of about 1 inch. The irregularly shaped foamed glass bodies intersect to define stacking angles of at least about 35 degrees. Under compression, the irregularly shaped foamed glass bodies crush and break up before slip failure occurs such that the roadbed has a crushing failure mode.

In the present invention, a multi-stage foam sound-absorbing black body material is provided for the first time. A graphene aerogel is introduced into a commercialized polymer foam skeleton by using a solvent plasticizing and foaming technology, so as to embed ultra-thin graphene drums in the foam skeleton. When sound waves enter the foam black body, a large number of graphene drums generate a severe resonance effect, thereby rapidly achieving attenuation of the sound waves, and combined with the friction loss of the porous structure of the polymer foam on the sound waves, excellent sound-absorbing performance is achieved in a wide frequency range. The present solution is provided on the basis of commercialized foam materials, has a simple method, low costs, and the potential of wide industrial application.
