| 摘 要： | 对78根钻孔桩和128根打入桩的承载力和端阻及侧阻的归－化参数进行了统计分析，通过比较发现，其分布宜采用对数正态分布，另外分别对钻孔桩和打入桩的整体可靠指标用校准法进行了计算，得到了其可靠指标分别为4．11和4．56，打入桩略高于钻孔桩。

| Abstract: | Statistical analysis on the bearing capacity of 78 bored piles and 128 drilled piles and on the normalized parameters of these piles' end and side resistance was carried out. It is found out by comparison that the ratios of the measured values to the calculated ones of the bearing capacity, the end resistance and the side resistance conform to lognormal distribution. Meanwhile, the total piles' reliability indexes are calculated by calibration method, with a result showing that the reliability of the bored piles is 4.11 and the drilled piles 4.56. |
