Influence of Thermal Condition on the Extraction Characteristics of Steel Strip Reinforcing Members

摘要

Cases of deformation in reinforced soil retaining walls have been reported in Hokkaido, Japan. Based on a survey of the deformed cases, the deformation was attributed to poor winter construction in which portions of the embankment soil froze and then subside during the thawing period, which resulted in bulging of the wall. In this study, to clarify how the temperature acting on the groundaffects the pulling resistance of the strip, pull- out tests were conducted under various embankment materials and curing conditions.The pulling resistance under the various construction conditions is discussed.
