LESSONS LEARNED FROM THE FAILURE OF A REINFORCED EARTH RETAINING STRUCTURE RESTED IN A LANDFILL
摘要
This paper presents an investigation on failure of a reinforced earth structure for retaining residual waste in a landfill site. The site is located in a hillslope. Noticeable lateral deformations are observed on the front face of the reinforced earth retaining structure after operation of the landfill for about 6 years, and considerable subsidence takes place in the reinforced earth retaining structure itself. Investigation on the causes for the failure of the reinforced earth retaining structure is carried out in terms of analysis of monitoring data on groundwater, geophysical explorations, and design aspects. A number of reasons are blamed for the failure of the reinforced earth retaining structure: (1) improper design and maintenance in the drainage system in the landfill; (2) neglect of the topography effect and subsurface flow induced by rainfall; and (3) lack of drainage measures on the back of the reinforced earth retaining structure.
