针对桩基工程中试桩过程复杂，费用高，一般试桩数量很少，以此推导桩的承载力存在很大的统计不确定性的问题，讨论了根据试桩结果计算桩承载力可靠度的方法，结果表明，在试桩结果平均值和标准差估计值相同的条件下，随试桩数量的增多，计算的可靠指标变大。%According to the complex test pile process, high cost, few test pile number in pile foundation engineering, this paper derived the sta-tistical uncertainty problems of pile bearing capacity, discussed according to method using the test pile calculation of bearing capacity, the test results showed that, under the same circumstances of test pile mean value and standard deviation estimate value, with the increase of pile num-ber, the calculation reliability index was bigger.
