Wiesner (2000) reported that the weight of an embankment built on soft subsoil would cause a concave ตั้ง profile. Due to the differential ตั้ง underneath the embankment, vertical stresses are expected to reduce in a zone along the centerline of the embankment and be transferred towards the toe. As such, the horizontal shear stresses will also increase towards the toe. This could cause the toe of the embankment to weaken.
