摘　　要：粉煤灰是路基填筑的常见材料,但早期强度及抗剪强度较差。通过外掺其他材料形成粉煤灰混合料,并进行抗压强度、水稳及回弹模量等大量试验,对普通粉煤灰经过掺合后的工程力学性质进行系统的研究和分析,进一步了解了外掺粉煤灰的各项工程力学性质。Fly ash is one of the main materials of subgrade filling, but its early strength and shear strength are poor. By adding other materials to form fly ash mixture, through pressive strength, water stability and resilience modulus, and so on, a large number of experiments such as com- the engineering mechanics properties of the ordinary fly ash after being added with other materials are studied and analyzed systematically, in order to under- stand the engineering mechanics properties of the additive fly ash.
