Geotechnical approaches for preservation of openly exhibited Geo-relics damaged by rainfall infiltration

Excavated geo-relics are vulnerable to damage by natural processes. The aim of this study is contribute the establishment a technical framework for preservation openly exhibited geo-relics. This also examines an geo-relic in Japan, which has experienced surface deformation soft soil layer due water infiltration. numerically investigated performing seepage-deformation analyses based on unsaturated mechanics order understand its mechanism and obtain effective countermeasures. results show that develops slope as bonding between particles, represented skeleton stress, decreases when infiltrates slope. Although calculation considers influence groundwater, well precipitation, primarily controlled not groundwater. Furthermore, elevation groundwater does development deformation. Based deformation, replacing with well-compacted, highly permeable proposed improve stability. It predicted method will be because replaced zone retains sufficient strength stiffness it wet, despite decrease stress rainfall countermeasure been adopted actual restoration damaged
