摘要: 本文根据上海及东南沿海软土地区的静力触探资料与118根钢筋混凝土打入桩静荷载试验对的比分析,提出了利用静力触探估算单桩极限承载力的经验公式。并对上述桩的估算结果进行了分析和评价。Abstract: This paper presents the empirical formulas for estimating pile bearing values based on static cone penetration resistance. The empirical formulas have been worked out on the basis of the data of static cone tests and the results thus calculated compared with those from vertical static loading tests on 118 reinforced concrete driven piles, in Shanghai and Similar Soft soils in Eastea China coastal regions, and also the results for estimating pile bearing capacity have been discussed.
