吹填砂的液化评估
Liquefaction evaluation of hydraulic fill sand
摘要
Abstract
There are many hydraulic fill projects on the overbank flood plain near river and sea.These projects not only utilize shallows-tidal-flat area but also benefit to dredge the waterways.Besides,the investment of developed land is rather low.Although the dredged sand has a higher strength,the earthquake liquefaction of sand should be considered.The U.S. Seed method and Japanese Road and Bridge Code are usually adopted for sand liquefaction evaluation.The adopted parameters,include the SPT blow count and CPT resistance.The two liquefaction evaluation methods are introduced,and their essence,difference and safety factors of liquefaction are analyzed in the paper.Then these methods are applied to evaluate a hydraulic fill project in Bangladesh.关键词
