Abstract
An in-situ reconstruction and extension structure of an embankment and a construction method thereof are provided. The structure includes a stepped slope excavated on an existing side slope. A gradient of the stepped slope is the same as that of an extension side slope, the stepped slope is individually intersected with top and bottom planes of existing side slope; a toe of existing side slope is taken as a toe of the extension side slope, and gradient of the extension side slope is determined according to positions of the toe and an expanded width. An outer side of stepped slope is filled with a geogrid reinforcement layer in a layered manner, a slope protection structure is arranged on an outer side of the geogrid reinforcement layer to form extension equivalent side slope; a drainage system is arranged at a bottom of the extension side slope.
