Stable roadbed structure

The utility model relates to a stable roadbed structure which comprises a stable frame, the stable frame comprises a plurality of cross beams and a plurality of longitudinal beams, and the cross beams and the longitudinal beams are arranged in a staggered mode; and the stable frame is filled with gravel. And the stabilizing frame can play a good role in stabilizing the gravel and prevent the gravel from generating transverse diffusion when being loaded, so that the gravel has high stability, the supporting effect of the gravel on the road surface is improved, and the stability of the road surface is improved. 本申请涉及一种稳定的路基结构，包括稳定框，稳定框包括若干个横梁和若干个纵梁，并且横梁和纵梁交错设置；稳定框内填充有砂石。稳定框能够对砂石起到较好的稳固作用，防止砂石在受载荷时产生横向扩散，使得砂石具有较高的稳定性，从而提升砂石对路面的支撑效果，提升路面的稳定性。
