DEFORMATION AND COUNTER MEASURE OF REINFORCED SOIL RETAINING WALLS AND EMBANKMENTS

Abstract

Due to climate change caused by global warming or increase in an earthquake, disaster risk of infrastructures increases in Japan. Reinforced soil retaining walls and embankments have high stability against earthquake or heavy rain so that construction results have increased continuously. However, there exist damaged reinforced soil retaining walls and embankments due to heavy rainfall or earthquake. This paper describes the damage, its cause and counter measure of damaged such structures. This paper also makes clear about the issue of conditions prone to deformation of such structures due to heavy rain or earthquake from the collected case studies.
