Abstract
A pre-disintegrated soft rock embankment structure based on spatial function zones and a design method thereof are provided. The embankment structure includes an embankment shear control zone, an embankment settlement control zone, and an embankment shear-settlement control zone. The embankment shear control zone is a zone in which a shear failure ratio is greater than a predetermined value. The embankment settlement control zone is a filled zone right below a top surface of an embankment. The embankment shear-settlement control zone is an intersection of the embankment shear control zone and the embankment settlement control zone. The provided structure and method improve the shear strength, stability, and durability, reduce footprint, shorten a settlement duration after construction, and solve engineering problems such as low slope ratio and large deformation of an embankment due to a long period of subsequent disintegration in the prior art.
