[Data] Learning from cases of embankment collapse caused by insufficient drainage.

Introducing the presumed causes and countermeasure proposals! Recommended use of high-pressure horizontal drainage materials.

This document includes lessons learned from the field trouble case "Landslide caused by insufficient drainage," outlining the estimated causes and proposed countermeasures. Due to the impact of heavy rainfall, large-scale collapses occurred on the slopes, including geotextile-reinforced earth walls, resulting in significant damage. The document explains the sites and causes of these incidents. Additionally, construction photos of the alternative materials for vertical drainage stone layers and horizontal drainage stone layers, "High-pressure drainage material public drain," are included, which can be useful for consideration during implementation.
