Abstract
The invention discloses a method for strengthening and widening subgrade with geocell based on conductive polymer, which belongs to the technical field of road construction. It includes the following steps: slope cutting and bench excavation for the existing embankment slope; leveling for the treated existing subgrade; filling and widening subgrade on the basis of the leveled existing subgrade; compacting the widened subgrade so that the compacted widened subgrade and the leveled existing subgrade are in the same plane; on the widened Subgrade The geocell based on the conductive polymer is tensioned and fixed for the first time; the geocell based on the conductive polymer is compacted to obtain the widened Subgrade of the geocell based on the conductive polymer. It can minimize the possibility of longitudinal cracks between the existing subgrade and the widened subgrade. In addition, it uses the conductivity of geocell based on conductive polymer to provide a material basis for monitoring the risk of cracks at the junction of the existing subgrade and the widened subgrade.
