| Abstract: | 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. |
