Abstract
In recent years, rainstorm disasters caused by global warming have frequently occurred in China. It has caused serious damage to artificial high embankments. In this paper, the influence of rainfall intensity, slope, and reinforced layers on the erosion and destruction of the artificial high embankment is deeply analyzed. Through the model test, the rainfall erosion prediction model is established. The results show that (1) the gully width, depth, and erosion amount increased with the increase in rainfall intensity and slope and decreased with the increase in reinforcement layers; (2) the final ditch shape of the embankment is influenced by steel bars; and (3) according to the model test data, the mathematical model of dike scouring is established. Rainfall intensity and the coupling between slope and reinforced layers are considered in the model. It can be used for predicting erosion during rainfall.
Highlights
There have been many rainstorms in China that are affected by global warming
When the slope gradient increased from 30° to 45°, the gully width increased by 4.8 cm, the depth increased by 4.5 cm, and the erosion amount increased by 4.8 kg. e main reason is that the slope gradient increases, the slope runoff velocity increases, and the erosion of rainfall on the embankment increases
Study on Prediction Model of Rainfall Erosion Damage to Reinforced High-Fill Embankment. e function model considers the influence of the above factors on the consequences of erosion disaster. e coupling prediction model with rainfall intensity, slope gradient, and reinforcement layers as independent variables and gully width and depth as the consequences of erosion disasters was fitted by IBM SPSS Statistics 26 ( )
Summary
There have been many rainstorms in China that are affected by global warming. E research on artificial embankment has been focused on rainfall and reinforcement (materials and methods) and achieved fruitful results. E research results can provide a reliable scientific basis for effectively forecasting rainfall landslide disasters of the reinforced artificial high embankment and have important theoretical value. To study the law of rainfall erosion damage to the embankment in the Chongqing area, referring to the previous research progress of embankment in Chongqing [22, 23], combined with the actual project in Chongqing, the test material was selected as the field clay of an embankment in Chongqing. Test Scheme. e slope is made by the layer pressure method, and each layer is piled up into soil piles with the same height according to the same mass of samples, and the soil is compacted from the same height by the compaction computer
