摘要
文章基于概率论与数理统计及可靠性分析理论 ,探讨了结构的可靠指标与岩土工程勘察中最小子样之间的关系。结果表明 ,在岩土工程分析与设计 ,若某参数对可靠指标具有较大的敏感性 ,则其取样数量必须足够多 ,否则会影响可靠指标的精确性。
In this paper the relationship of the reliability and the least sample number in geotechnical prospecting is studied. The results show that the sample numbers must be many enough if some parameters are very sensitive to the reliability index, otherwise the reliability index would not be accurate.
