结合三项典型的工程实例,揭示了现状岩土工程勘察工作中地下水化学性质分析观念的混乱及其影响评价技术手段的缺陷。提出了地下水化学性质样本统计分析的标准技术工作模式,并对实际运用中需要注意的问题给予了说明。论述了依据样本真值和中值差等统计分析参数施行可靠性评价的意义,探讨了改进途径和进一步规范相关技术工作的措施,包括地下水样本数量限定技术标准和异常实验数据的判别及处理等。就规范相关技术工作程序提出了建议。
Combining with three typical engineering examples, the disorganization of the concept of groundwater chemical properties analysis in the current geotechnical engineering exploration and the defects of the technical means influencing the evaluation are revealed. The standard technical working mode of statistical analysis of groundwater chemical properties was put forward, and the problems needing attention were pointed out. The significance of reliability evaluation based on statistical analysis parameters such as sample truth value and median value is discussed, and the ways of improvement and the measures to further standardize the related technical work are discussed, including the identification and treatment of the technical limit of groundwater samples and abnormal experimental data . Put forward suggestions on standardizing technical work procedures.
