Failure Mechanism of Jinjiang Riverbank Based on Geotechnical Properties of Soil

Abstract:

In this paper, concerning the geotechnical properties and erosion circumstances of Jinjiang riverbank of Yangtze River, field on-site investigation and soil laboratory tests were conducted. Study results reveal that the soil of Jinjiang riverbank contains mostly the silt particles with 24% of clay content, the unconfined compressive strength of the soil decreases rapidly and permeability have a significant increase with the small change in water content, which are considered to be primary factors of occurrence of riverbank collapse when flooding occur. In addition, it is cleared that collapse process of riverbank are mainly due to the formation of tension crack and toppling behind the bank face.
