Design and Performance of a 46-m-High MSE wall-edge

Geotechnical cross-section diagram of the Sea-Tac Airport Third Runway embankment, showing soil layers including stiff sandy peat, glacially overridden sand, and a subgrade improvement zone. The diagram details instrumentation locations (strain gages, Sondex rings, inclinometers with piezometers) and structural elements including reinforced fill limits and common embankment fill, with the runway centerline approximately 120 meters from the embankment toe.
