摘　　要：大型航空货站的站房具有面积大、荷载大的特点,对地基承载力有较高要求。针对大型货运区站房工程,提出了减沉疏桩的地基加固方案,通过现场试验和有限元模拟证实了减沉疏桩可以有效控制货站站房地基的工后沉降,并根据试验结果对减沉疏桩的加固工艺提出了优化。The station building of a large air cargo terminal has the characteristics of large area and large load,and has high requirements for the bearing capacity of the foundation.In view of the station building project in large freight area,a foundation reinforcement scheme of settlement reduction sparse pile is proposed.Through field test and finite element simulation,it is verified that the settlement reduction sparse pile can effectively control the post construction settlement of the freight station building foundation.Based on the test results,the reinforcement technology of settlement reduction sparse pile is optimized.
