摘　　要：文章介绍人工挖孔扩底桩的计算方法 ,并提出桩身设计与构造要求 ,在地基稳定且承载力较高的情况下 ,采用人工挖孔扩底桩修建荷载较大、多层框架结构的变电站建筑 ,可与高层建筑一样取得质量好、工期短、沉降小、造价低的效果。This paper introduces the calculation of manually excavated large diameter piles with enlarged basement, the requirements of their design and structure. In cases of stable and higher bearing capacity of the foundation, with this kind of piles, any multi-floor skeleton structure building for substation with heavier loading can be built in good quality, short time, low settlement, and low cost, as well as for high buildings.
