摘　　要：随着机制砾砂及喷射混凝土在工程中的广泛应用,机制砾砂喷射混凝土的应用已引起工程建设者的重视。结合某公路边坡机制混合砾砂喷射混凝土加固工程,通过现场试验及采样分析,开展机制混合砾砂的生产、砾砂喷射混凝土的配合比设计及施工工艺的研究,从而得出了一些有益的结论,为机制砾砂喷射混凝土在工程中的应用提供有益的借鉴。With the extensive using of the machine-made sand and shotcrete in engineering, the application of the machine-made gravel sand shotcrete is emphasized by constructor. Combined with the reinforced engineering of the machine-made gravel sand shotcrete on the highway slope, the production of machine-made gravel sand and the mixture ratio design and construction technology of the gravel sand shotcrete are studied through the field experiments and the sampling analysis. The beneficial conclusions that are used for reference of the application of the machine-made gravel sand shotcrete are gained.
