摘　　要：阐述了后注浆工艺提高承载力的机理 ,根据钻孔桩后注浆工程的施工经验 ,建立了单桩承载力理论计算经验模式 ,并通过实例验证表明 ,该经验模式可满足承载力理论计算要求 ,使钻孔桩后注浆工艺中单桩承载力的计算有据可依 ,具有一定的实用价值 .According to the construction experiments of the later grouting of the drilling_hole piles, an experiened model of the theorestical calcalation for the bearing capacity of the sigle pile is set up. The tested examples have shown that this model can meet the need of the theoretical calculation of the bearing capacity.
