摘　　要：本文通过上海机床电器三厂综合楼桩基的施工实例,介绍了夯扩桩的施工工艺和特点,讨论了夯扩头形状和体积的计算方法,分析了扩大头对单桩承载办的影响及规律。文章认为,夯扩桩承载力较高,成本低、工效高、污染小,是一种可用于上海地区多层建筑基础的桩型。Based on the actual construction of the pile foundation of the Shanghai Third Machine Tool Electric Applicance Factory, the features and the construction process of the expanded base pile, the shape of the pile and the method of calculation of the volume are presented in this paper. The bearing capacity of the expanded base pile and the construction efficiency are high with lower cost and less pollution. This type of pile can be used widely in Shanghai for high-rise buildings.
