## 5 Conclusions  
This paper conducted model experiments on roadbed slopes that were supported by wooden framework beams and bamboo anchor systems under train loads. Three-dimensional numerical simulations were performed to analyze the effect of train load frequency, peak difference, and peak value on the soil pressure of the roadbed slope. They also analyzed the horizontal displacement of the slope surface, the internal forces within the supporting structure, and the slope safety factor. The relevant conclusions are as follows:  
1. When the loading frequency increases from 2 Hz to 3 Hz, there is a considerable increase in soil pressure; however, further increments in the loading frequency result in a smaller increase in soil pressure. The increase in dynamic load shows a positive correlation with soil pressure. 2. In indoor slope model experiments, the axial force on the anchor rods is not uniformly distributed. Therefore, in engineering design, the assumption of uniform axial force distribution along the length of the anchor rods is deemed unreasonable. Across various conditions, the axial force on the rod tends to be greater closer to the top of the slope. The support system primarily operates with the top-slope anchor rods and then gradually transitions to the anchor rods in the middle and at the foot of the slope. The combined action of the anchor rods and wooden framework beams forms an integral support system that resists slope movement, thereby enhancing slope stability. 3. The point of maximum bending moment in the anchor rods gradually transitions from the anchor head to the anchored end with increased burial depth. The bending moment is significantly influenced by loading frequency, increasing with higher loading frequencies. It shows minor fluctuations with variations in upper and lower peak values. Notably, the bending moment is prominently influenced by increased upper peak values, exhibiting a decrease with their rise. This phenomenon might be due to the larger peak difference, causing the combined wooden framework beam-bamboo anchor support system to resist slope movement. 4. When employing the wooden framework beam-bamboo anchor support as temporary support in engineering applications for roadbed slopes, it is crucial to monitor and protect the positions at the slope's top and bottom. Additionally, enhancing the overall integrity of the wooden framework beam-bamboo anchor support is recommended. 5. Under the influence of train loads, the roadbed slope with wooden framework beam-bamboo anchor support effectively mitigates the impact of dynamic train loads. The safety factor of the roadbed slope is increased by 20.13% compared to the unsupported condition, significantly enhancing slope stability. Figure 26: Maximum shear stress on the slope.
