摘　　要：随着机制砂及喷射混凝土在工程的广泛应用,机制砾砂在喷射混凝土中的应用已引起工程建设者的重视。本文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,进行机制混合砾砂的生产、砾砂的性能、砾砂喷射混凝土性能的研究,探索砾砂在喷射混凝土中的应用,从而得出了机制混合砾砂完全可作为喷射混凝土的骨料的有益的结论。With the extensive use of the artificial sand and shotcrete in engineering,the application of the artificial mixed gravel sand in shotcrete have been emphasized by constructor.This paper combines with the reinforced engineering of the artificial mixed gravel sand-shotcrete on the highway slope,the production of artificial mixed gravel sand the characteristic of the gravel sand and the gravel sand-shotcrete is studied through the field experiment and the sampling analysis,and the application of the artificial mixed gravel sand in shotcrete is explored,and the beneficial conclusions that the artificial mixed gravel sand can be used as the aggregate of the shotcrete.
