An Investigation and Analysis of How Side-hill Gravity Retaining Walls Failed During the Wenchuan Earthquake

摘要：

On May 12, 2008, an earthquake measuring eight on the Richter scale happened in Wenchuan County in the Sichuan Province of China. Occurring in a mountainous area, the earthquake greatly damaged side-hill retaining walls, and especially gravity retaining walls. From a comprehensive investigation and summary of road damage conditions from the disaster area, this paper summarizes five characteristic failure types, namely, wall cracking, partial wall failure, wall segment extraversion, wall segment slip and retaining wall failure by rock-fall. Combining site observations and theoretical analysis, this paper discusses the likely reasons for each failure mode and proposes anti-seismic countermeasure designs.
