Geotechnical Health Assessment of Roadway Embankment Using Airborne LiDAR
Excessive erosion was observed within the slopes of a 1.3 km long earth embankment supporting an active roadway. The embankment extends up to 15 m above the bottom of an adjacent river. The slopes exceed 1 horizontal to 1 vertical (1 Hz: 1Vl) in some locations and are mostly covered with vegetation. Airborne LiDAR technologies were used to capture the existing topography and generate a digital terrain map which was used to determine changes in elevation and calculate the degree of steepness. The subsurface soils consist of high quantities of silts indicating a high susceptibility to erosion. The current embankment health was assessed by evaluating the stability of the slopes using surface and subsurface information. Several mitigation schemes were developed to increase the health of the embankment and protect the existing roadway. The selected scheme considered multiple aspects including surface drainage, constructability, and cost.
