圆筒基础的设计与施工

Round Bucket Foundation Design and Construction

建筑物基础的种类很多,相比之下,圆筒基础既具有挖孔桩的优点,又克服了沉井的弊端,而且能减小基础自重、基底面积、混凝土体积和配筋量,从而降低工程造价。文章重点探讨了圆筒基础承载力、筒壁计算及构造、底板计算、承台计算等圆筒基础设计问题,介绍了圆筒基础施工工艺及质量控制要点,并结合工程实例说明圆筒基础的设计效果。实践证明,圆筒基础具有良好的经济性和实用性,可在建筑工程中广泛应用。

There are kinds of building foundations.By comparison,the round bucket foundation has the same advantage as drilling hole pile,and overcomes the same shortcoming as open caisson.Also it can reduce the sole weight of foundation,basement area,concrete volume and reinforcing steel weight, and lower the engineering costs.The paper discusses mainly the problems concerning the bearing capaci-ty,the wall calculation and its structure,the calculations of base plate and capping of round bucket foundation.It introduces the main points of construction procedure and quality control of the foundation,illustrates the design effectiveness of the foundation in connection with practical engineering examples.It has been proved by engineering practices that the round bucket foundation has good economical and practical features and can be applied in architectural engineering.
