- Abstract:
- To explore the road construction technology across the mined-out area, the relative position between goaf and road and the active state of the mined-out area were considered to analyzed the deformation law of subgrade. The improved creep constitutive model was adopted to simulate settlement and horizontal displacement of road. The critical safety range for road construction was determined in the mined-out area. The prediction model of subgrade settlement was proposed and compared with the accrual engineering monitoring data. The result shows that the model calculation results are in good agreement with the actual data, and the prediction model can be applied to the design and construction of the road above the mined-out area.
