摘　　要：桩体与桩间土共同作用承担荷载的复合地基理论已被广泛应用。在深厚软土地基中采用长短桩复合地基既可有效提高地基承载力又能减小沉降。本文通过工程实例,简要介绍了在污水处理厂工程中采用双灰桩与沉管灌注桩两种桩型共同加固软弱土的方法。The theory of pile composite foundation has been applied willy. For deeply thick soft soil, the subagrade bearing capacity can be increased and the settlement of construction can be reduced effectively through applicating the long ＆ short pile composite foundation. In this paper, a new composite foundation applied in one sewerage project was introduced, which includes burned lime ＆ fly ash pile and cast-in-place pile with driven casting.
