PHYSICAL SIMULATION EXPERIMENT FOR CHARACTERISTICS OF LOESS SLOPE EROSION

Huang Xiaoh

Abstract

The erosion is the main cause of natural disasters of the loess highway slope. This paper uses the slope erosion experiment with simulated rainfall model. It can reproduce the splash erosion slope,sheet erosion,gully erosion,and collapse of basic failure process of slope. It can make detailed description and analysis of the process of erosion. The experiment shows that erosion sediment per unit area increase gradually with the increase of experiment slope and total runoff. The erosion sediment decreases gradually with the increase of experiment slope.Meanwhile,there is a corresponding relationship among the main parameters of loess slope erosion such as total erosion runoff,confluence sediment,erosion sediment,and rainfall intensity.
