摘要
合理子样数应随土的性质、指标特征、土样质量和工程要求而异。本文在分析了沿海平原各主要土层的物理力学性质指标变异性的基础上 ,运用概率统计方法 ,针对不同土层不同的物理力学性质指标提出了岩土工程勘察合理子样数确定原则。
The reasonable number of samples depends on the properties of soil, characteristic of indexes, quality of samples, and requirements for the engineering project. On the basis of analysis of variation of physical and mechanical indexes of each major soil layer in coastal plain, the reasonable number of samples for geotechnical engineering prospecting is suggested in the light of different physical mechanical indexes of different soil layers by using probability statistical method.
