摘　　要：本文通过对全国十省两市的275根入土深度H=4.09～60.05m的钢筋混凝土打入桩的静载试验资料与相应的201个静力触探孔的对比、分析后,提出了桩端阻力与桩侧摩阻力的估算方法。发现单桩极限承载力的估算值与实测值比较接近。Empirical formulas for evaluation of skin friction and end bearing capacity based on static cone pen-tration resistance are presented. The empirical formulas have been worked out on the basis of the data of 201 static cone tests and the calculated results have been compared with those from vertical static loading tests on 275 reinforced concrete driven piles, 4.09-60.05m in the depth of embedment of the layer, in 10 provinces and 2 cities in the nation. It is found that the results from evaluation of single pile agreed well with the observed values from static loading tests on piles.
