Abstract：Abstract：Research purposes： In this paper, the settlement deformation characteristics and control effect of a new type of geotechnical grid reinforced roadbed structure is studied by the numerical simulation and field experiment, which is inexpensive, easy construction, good earthquake resistance, environmental and landscaping, and the research conclutions provide basis for the application of this structure in similar engineering. Research conclusions： (1) Numerical analysis and field experiment show the new structure can meet the design requirement for foundation settlement and the technology is feasible. (2) The new structure retains the pattern and effect of the original roadbed structure, and could reduce the foundation reinforcement of the slope of the embankment on the premise of the embankment stability. The scale and quantity of the material of foundation reinforcement is reduced. (3) The new structure is suitable for subgrade bed of soft clay foundation in railway and highway constructions.
