《地下水化学影响的岩土工程勘察评价》一文的商榷

Discussion on the article “Chemical influence of groundwater evaluation for geotechnical study”

现行《岩土工程勘察规范》(GB 50021-2001)对地下水有专门一章内容进行规定,对水样的采取、试验、腐蚀性评价也有原则性规定。《地下水化学影响的岩土工程勘察评价》一文根据3个工程项目的实例,对所取的样品进行了简单的分析,提出用平均值和标准值来进行评估地下水。笔者根据现行规范规定和大量的工程实践认为,该文中许多论点与事实有一定的差距,与岩土工程地质条件、水文地质条件的基础理论有一定的相悖,且在工程实践中操作的可行性也较差。现从实验数据及样本真值、样本数据、分析模型、异常数据处理等方面与该文作者作一探讨。

The existing ＂Code for Investigation of Geotechnieal Engineering＂ （GB 50021 -2001 ） has a special chapter on the content requirements of groundwater, in which the taking of water samples, testing and corrosion evaluation are also provided fundamentally. Based on three engineering examples, the article ＂Chemical Influence of Groundwater Evaluation for Geotechnical Study＂ carried out a simple analysis for the samples and put forward that the assessment of groundwater was made by using the mean value and standard value. Based on the current specifications and a lot of engineering practices, the author believes that there are some differences between the arguments and the facts which contrary to certain basic theory of the geological conditions, geotechnieal engineering and hydrogeological conditions, and the feasibility of the engineering practice is also poor. The author wishes to discuss the experimental data, the true values of samples, the sample data, the analysis model, the handling of exception data and other aspects of the data with the writer of the article.
