It studied the deformation characteristics of the Prefabricated bamboo reinforced porous concrete slab through points with four points focused beam loading method. The results show that flexural behavior of precast slab can be improved by adding bamboo rein-forcement. Along with the increase of bamboo reinforcement ratio, deflection of precast board will gradually reduce. Through the loading deflection curve, we can discover that the bamboo reinforced precast slab with the linear elastic state, and the slab can withstand a certain load after cracking. Bamboo reinforced with strengthening and toughening effect for porous concrete, prefabricated bamboo reinforced porous concrete plate can be used better in slope protection engineering.%采用加分配梁的四分点集中力加载方式研究加入不同配筋率的竹筋多孔混凝土的变形特性。试验表明竹筋能显著改善预制板的抗弯性能，随着竹筋配筋率的增加，预制板的跨中挠度会逐渐减少。通过荷载-挠度曲线，发现未开裂前的竹筋预制板呈线性弹性状态，且开裂后还能承受一定的荷载。竹筋对多孔混凝土有很好的增强增韧作用，预制竹筋多孔混凝土板可以更好、更稳定的在边坡防护中进行工程应用。
