摘　　要：长螺旋钻孔压灌混凝土旋喷扩孔桩(简称WZ桩),是一种摩擦加端承桩,适用于地下水位以下的黏性土、粉土、砂土、淤泥及碎石土等复杂地质条件,适应地层广泛、承载力值高、无污染等。文中对其应用进行探讨,为今后在同类地区的设计和施工提供了参考。Grouting pile reaming concrete （WZ pile） of long spiral bored is a kind of friction and end-burden pile, suitable for underground cohesive soil, water silt, sand, silt and gravel soil with complex geological conditions, adapting to varieties of strata with high burdening capacity and without pollution. Discussion of the application in this paper proposed some ref- erence for design and construction in similar areas.
