摘要
介绍大直径钻孔灌注桩的技术特点 ,以及目前在欧、美的应用概况。通过对欧洲一些国家桩基础设计规范的研究 ,分析了单桩抗压的工作机制。通过试桩的静载荷试验和应力测试 ,对桩侧极限摩阻力计算方法和经验公式进行了系统讨论。并阐述了桩基设计中 。
This paper introduces the technical characteristics of large diameter bored piles(LDBPs), particularly the application of LDBPs to Bridge Engineering in Europe and USA. As a result of the research on the codes of piles published in some countries in Europe, the working mechanism of a LDBPs is analyzed. Based on the static load tests for the instrument piles, the static calculation and the empirical formula of determining the ultimate shaft friction resistance of a LDBPs aree discussed systematically. Further more the concept and influence of serviceability rules on design for LDBPs foundation are summarized.
