摘　　要：文章通过三轴不固结不排水剪切试验和现场施工验证,综合考察了洞渣掺入率、含水率和围压对改良隧道洞渣材料力学性能的影响。研究结果表明,在隧道洞渣掺入比例为40%和24%最优含水率条件下,改良材料作为路基材料,在实际工程中其抗剪强度与实验室结果基本一致,施工过程质量控制良好。This paper comprehensively investigates the infl uence of slag incorporation ratio,water content and confi ning pressure on the mechanical properties of improved tunnel slag materials by triaxial unconsolidated undrained shear test and field construction verification.The results show that under conditions of the tunnel slag incorporation ratio of 40%and the optimal moisture content of 24%,the improved material used as the subgrade material has basically the same shear strength with the laboratory results in the actual engineering,and the quality control of the construction process is good.
