摘要
基于植被混凝土技术的边坡生态防护是岩质边坡生态建设的一项常用技术,防护基材的耐久性直接影响边坡防护的长期效果。通过设计实验方案,对不同配合比基材的水稳定性和抗冲刷能力进行了研究。研究结果:基材不同配合比的7 d龄期之内水稳强度降低较小,超过7 d后,随着基材强度提高,饱水浸泡的试块水稳强度降低幅度较大,在工程中采取措施避免基材收到水体长时间浸泡。基材3 d抗冲刷能力较差,但7 d后抗冲刷能力明显提高,在施工过程中加强坡面初期防护工作。
The slope ecological protection based on vegetation concrete technology is a common technology in the ecological construction of rock slope,and the durability of the protection substrate directly affects the longterm effect of slope protection.In this paper,the water stability and scouring resistance of base materials with different mix ratios are studied by designing experimental schemes.The results show that the water stability strength of the test block soaked in water decreases significantly with the increase of the strength of the base material after 7 days.Measures should be taken to prevent the base material from being soaked in water for a long time in the project.The anti-scour ability of the base material is poor in 3 days,but the anti-scour ability is significantly improved after 7 days.The initial protection of the slope surface shall be strengthened during the construction process.
