This paper proposes a new method for initial support of the slope with bamboo anchors and wood frame beams. The structure is mainly used to ensure the stability of the slope during the period when the plant root system is not yet developed, and it has certain guiding significance for ecological slope protection engineering. In this paper, a group of unsupported slopes and three groups of bamboo anchor and wood frame beam slope model tests with different support forms are carried out. By analyzing the soil failure of the four groups of slopes, the horizontal displacement of the slopes and the stress distribution of the bamboo anchors, the optimal support form is obtained. Its analysis shows that: Appropriately reducing the arrangement spacing of bamboo anchors and wood frame beams can significantly improve the support effect, but when the spacing between bamboo anchors and wood frame beams is reduced to a certain value, the improvement of the support effect is no longer obvious. Considering the support effect and cost of bamboo anchors and wood frame beams comprehensively, it is the most cost-effective to support the test slope with three rows of bamboo anchors and wood frame beams. Under the load of the top of the slope, the horizontal displacement of the top of the slope occurs before the bottom of the slope, but the final displacement of the bottom of the slope is larger than that of the bottom of the slope. The stress variation laws of bamboo anchors at different positions are different. Due to the load on the top of the slope, the stress value of the upper bamboo anchor is generally greater than that of the lower bamboo anchor.
