###### Abstract  
In order to investigate the dynamic response of embankment slopes supported by wooden frame beams and bamboo anchor rods under train loading, this study conducted model tests on embankment slopes supported by wooden frame beams and bamboo anchor rods and carried out three-dimensional numerical simulations of the slopes. This study focused on analyzing the effects of train loading frequency, the peak value difference, and the peak value of the soil pressure on the embankment slopes. This study also analyzed the horizontal displacement of the slope surface, the internal forces in the support structure, and the slope safety factor. The results indicated the following: (1) The increase in loading frequency from 2 Hz to 3 Hz resulted in a significant increase in dynamic soil pressure, with a smaller increase observed upon further frequency increments. Moreover, increasing the load or peak value difference led to an overall increase in the maximum dynamic soil pressure. (2) Under various loading conditions, the axial force in the top anchor rod was significantly greater than that in the middle anchor rod. Additionally, the axial force in the rod body exhibited a pattern of larger forces near the anchorage end and smaller forces near the anchor head. The location of the maximum bending moment in the anchor rod transitioned from the anchor head to the anchorage end as the slope depth increased. The bending moment of the anchor rod increased with the loading frequency but decreased with an increase in the peak value, showing a minor influence from the upper and lower peak values. (3) With the presence of this support system, the slope safety factor increased by 20.13%. A noticeable reduction in the horizontal displacement of the slope surface was observed, with the greatest reduction in the top slope area, followed by the slope angle. b amboo anchor; timber-frame beam; roadbed slope; slope support; dynamic response 2024

[4] established a three-dimensional numerical root model consisting of an inverted t-shaped rootstock and limiting hairy roots based on the actual root morphology in order to study the shear strength characteristics of the soil root system in Makino bamboo forests and successfully applied it to the numerical simulation of in situ uprooting tests of the soil root system. This paper proposes a vegetation slope protection method that uses the combined support of live stumps and bamboo anchors [5; 6]. Addressing the initial stage of live stump root development, a stage in which it fails to provide deep-root anchorage and shallow-root reinforcement to the slope [7; 8], temporary support is applied to the roadbed slope using bamboo anchors and wooden frame beams. Previous studies have conducted experiments and three-dimensional numerical simulations on the use of wooden frame beam-bamboo anchor support systems under static loading conditions for slope protection. [PERSON] et al. [9] introduced an ecological slope-protection method--bamboo anchor wooden frame beams for initial support and indoor physical model experiments were conducted. Results indicated that under static loading, horizontal displacement initially occurred at the slope crest, but, ultimately, the horizontal displacement at the slope base exceeded that at the crest. [PERSON] et al. [10] performed indoor model experiments on four different forms of support using wooden frame beam-bamboo anchor systems for slope protection. The experiments demonstrated the significant effectiveness of the wooden frame beam-bamboo anchor support system, and optimizing the spacing between bamboo anchors and wooden frame beams enhanced its supportive effects. [PERSON] et al. [11] conducted indoor model experiments applying static loads at the slope crest using the wooden frame beam-bamboo anchor support system.
