摘　　要：简要介绍了大直径挖孔扩底灌注桩的承载机理和破坏机理以及其设计中需要考虑的因素和单桩承载力特征值计算方法。并以中联水泥南阳分公司6000t/d熟料生产线应用情况为例,演示了大直径挖孔扩底灌注桩的计算过程、结果分析以及桩身参数的确定。应用实践证明,该类桩的应用既节约投资成本,又缩短了施工工期,效益明显。The load and destroy mechanism of large-diameter cast-in-situ piles with enlarged bases was introduced in brief as well as the factors designer should consider and the calculating methods for the load eigenvalue of a single pile. By example of the application of 6 000 t/d cement clinker production line of China United Cement Nanyan Company, demonstrated the calculating process and the result analysis. The practice proves that this kind of pile adopted,the cost will be saved and the constructing time will be shorten, the benefit is evidence.
