Research the groundwater seepage field of Chengdu boat-shaped coffin relics with numerical simulation technology

摘要

Chengdu boat-shaped coffin relics is a large-scale tomb of Warring states period.The investigations on the spot indicated that alternate circulation and fluctuation of groundwater level had already destroyed archaeological sites and ruined cultural relics.This is the main environmental geological reason to cause destruction of archaeological sites.So it was essential to investigate in detail how groundwater corrode the site and the relics,and to take preventive measures according the geological characteristic of the site.The numerical simulation technology was adopted the to help investigate the seepage field of groundwater,and research the relationship of groundwater with protective engineering.Then the blind ditch was put forward to prevent the sites and relics from the corrosion of groundwater.And then the numerical technology was used to forecast the change of groundwater after putting the protective measures.
