| 摘 要： | Along with the reduction of sediment yield of the Huanghe (Yellow) River, the erosion of the Huanghe River Delta aggravates, which has becomes an important factor that threatens the coastal protection structures. Starting from the study of the erosion resistibility of the sediment, this paper explores the internal mechanism of erosion phenomenon. This paper takes Diaokou as the study area and takes soils as samples which are mixed with clay into reconstructed samples whose ratio of clay content are 5%, 10%, 15%, 20% respectively, then dynamic tri-axial apparatus is applied to simulate wave loads of different intensity; then the resistibility of soil to erosion is determined via concentrated flow test and the structural property is determined via the disintegration test. Finally, the resistibility to erosion and the structural property of the non-compressed soil samples are compared with the compressed data. The results indicates that liquefaction failure exerts significant influence on the resistibility to erosion and the structural property of the silty soil in the Huanghe River Delta. Therefore, in the future erosion studies, the liquefaction phenomenon shall be fully considered.

| Abstract: | Along with the reduction of sediment yield of the Huanghe (Yellow) River, the erosion of the
Huanghe River Delta aggravates, which has becomes an important factor that threatens the coastal
protection structures. Starting from the study of the erosion resistibility of the sediment, this paper
explores the internal mechanism of erosion phenomenon. This paper takes Diaokou as the study
area and takes soils as samples which are mixed with clay into reconstructed samples whose ratio
of clay content are 5%, 10%, 15%, 20% respectively, then dynamic tri-axial apparatus is applied
to simulate wave loads of different intensity; then the resistibility of soil to erosion is determined
via concentrated flow test and the structural property is determined via the disintegration test.
Finally, the resistibility to erosion and the structural property of the non-compressed soil samples
are compared with the compressed data. The results indicates that liquefaction failure exerts
significant influence on the resistibility to erosion and the structural property of the silty soil in the
Huanghe River Delta. Therefore, in the future erosion studies, the liquefaction phenomenon shall
be fully considered. |
