In this article, the basic parameters of C80F350 artificial sand concrete mixture ratio is determined, and its workability, mechanical properties and durability are tested. Pilot production of artificial sand concrete pipe pile is conducted. Pile bending test and pile dice antipressure and antifreezing test are carried out. The results show that:the mixed sand of machine-made sand and natural sand mixed together in definite proportions can make C80F350 artificial sand concrete which has the same excellent performance with natural san concrete; Compared with natural sand concrete, C80F350 artificial sand concrete higher compressive strength and splitting tensile strength, better frost resistance and permeability resistance, lower chloride ion permeability coefficient and bigger elastic modulus; C80F350 artificial sand concrete is conformed to the existing pipe pile production process, and the pipe pile body bending capacity, dice compressive strength and durability properties can meet the related requirements.%本文确定了C80F350人工砂混凝土配合比的基本参数，测试了其和易性、力学性能及耐久性能，并进行了人工砂混凝土管桩试生产，对桩体进行了抗弯试验，对桩体切块进行了抗压及抗冻试验。结果表明：（1）采用现有机制砂与天然细砂按一定比例混合而成的混合砂可以配制出与天然砂混凝土性能同样优异的C80F350人工砂混凝土；（2）C80F350人工砂混凝土与天然砂混凝土相比具有抗压及劈裂抗拉强度高、抗冻及抗渗性好、氯离子渗透系数低、弹模大等特点；（3）C80F350人工砂混凝土与现有管桩生产工艺相适应，管桩桩体抗弯性能、切块抗压强度及耐久性能均能满足相关要求。
