Abstract

Oil spill accidents from ships in inland rivers often occur. In order to understand the adsorption characteristics of oil spills on the sandy beach boundaries of inland rivers, a generalized adsorption test was carried out in the flume. This paper firstly establishes the thickness-grayscale relation of oil spilled oil film based on the hydrostatic calibration test. By carrying out a generalized experiment on sandy river bank oil spill adsorption, the quantitative relationships among the oil spill adsorption amount, adsorption rate, and time per unit length of the sandy boundary were established. The results show that with the oil spill expansion and adsorption, the amount of oil spilled on the boundary of unit length has an exponential relationship with time, and the adsorption rate has a logarithmic relationship with time. The parameters in the fitting formula are analyzed. The research can provide a certain basis for oil spill expansion adsorption research and accident handling in inland waterways.
