摘　　要：结合现浇薄壁管桩(PCC)在盐通高速公路桥头软基加固中的应用,通过一系列现场试验观测对现浇薄壁管桩复合地基的桩土荷载分担、沉降、桩土差异沉降、路堤稳定性等的变化规律进行了探讨。观测表明,PCC技术可显著减小地基的沉降量,使用该技术加固后地基具有沉降收敛快、工后沉降小的特点。Based on the application of cast-in-place thin-wall concrete pile (PCC) in Yan-Tong Expressway, a series of field experiments and monitoring are conducted. The characteristics of load sharing, settlement and differential settlement and embankment stability are discussed.
