EXPERIMENT OF STRENGH DETERIORATION OF SILT CURTAIN IN SEA ENVIRONMENT

Abstract

 Damage of silt curtain used for pollution control during construction may cause serious environmental problem. Evaluation of strength of silt curtain is very important to prevent damage of silt curtain, however, to date there exists very limited data on the relationship between duration of construction and strength deterioration for silt curtain. In this study, we set silt curtain in sea environment for 13 months and monitored the strength deterioration of silt curtain month by month. Relationship between strength deterioration and hours of sunlight and temperature is also discussed.
