摘　　要：通过对水质进行简分析,以了解其物理性质,并得到相关物性指标参数。水质简分析成果中的物性指标主要包括:pH值、矿化度和溶解性总固体。测定这些物性指标的方法有多种,但受不同环境和其他干扰因素的影响,这些测定方法各有其特点和相应的使用条件。通过对水质中pH值、矿化度和溶解性总固体采用不同的测定方法进行分析,提出了选择合适的测定方法,为工程勘察提供可靠的物性分析数据。In this paper,the water quality is briefly analyzed to understand its physical properties and get the related physical property index parameters.The physical property indexes in the results of water quality analysis mainly include:pH value,salinity and dissolved total solids.There are many methods to determine these physical properties,but affected by different environment and other interfering factors,these methods have their own characteristics and corresponding conditions of use.In this paper,the pH value,salinity and total dissolved solids in water quality are analyzed by different determination methods,and it is suggested that only by selecting appropriate determination methods can reliable physical property analysis data be provided for engineering investigation.
