摘要

Geosynthetic drains (random wire core and needlepunched nonwoven filter) were excavated at 6 landfills after 12 years of service and 1 bank amelioration after 20 years of service. Technical characteristics and durability information from stabilizer analysis are reported. Service life up to 110 years was calculated.
