The invention discloses a hidden retaining roadbed structure, wherein a retaining wall(s) is/are arranged at one side or two sides of a rectangular region on a roadbed with a trapezoidal section and a plurality of consolidating piles are vertically arranged at intervals in the foundation soil which is arranged at the lower part of the rectangular region simultaneously. Furthermore, a pile block cushion course is arranged horizontally at the top of all consolidating piles. In the hidden retaining roadbed structure, the retaining wall(s) made from wrapped reinforced earth structures arranged in layers is/are arranged at one side or two sides of the rectangular region on the roadbed with a trapezoidal section. The influence range of road load can be limited within the retaining wall if the retaining wall is arranged in the influence range of the road load as the retaining wall has good quack-proof performance, thereby greatly reducing the reinforcement range of the foundation under the roadbed based on the guarantee of subsidence control effects so as to be capable of effectively reducing construction investment. Additionally, greening can also be conducted on side slopes to obtain better landscape effect without any change in the conventional trapezoidal section shape of the roadbed. Furthermore, the structure is convenient for maintenance and repair of road.
