由美国土木工程学会环境和水资源研究所标准发展委员会KSTAT标准委员会编制细粒土饱和导水率计算是一系列标准中的第四个标准，该系列标准增强了对关键地下水参数行为的概率表征和理解，饱和导水率。标准ANSI/ASCE/EWRI 65-17提供了计算细粒土饱和导水率（Ksat）、渗透性和孔隙度的指南。计算包括四个部分:阶跃载荷试验的应变应力数据；与固结系数有关的一维竖向固结理论；渗透性与渗透性的关系；以及孔隙度和土壤孔隙比之间的关系。 这个标准？s方法可用于完善或改进地面沉降计算、地下水流量预测和地下水中溶解溶质运移。本标准中的方法仅限于细粒、可压缩的无机土壤。高有机土（泥炭）表现出异常的一次和二次固结，不在本标准范围内。标准ASCE 65-17将对环境工程师、水资源工程师和任何在工程中使用液压的人有用。

Prepared by the KSTAT Standards Committee of the Standards Development Council of the Environmental and Water Resources Institute of the American Society of Civil EngineersCalculation of the Saturated Hydraulic Conductivity of Fine-Grained Soils is the fourth standard in a series that enhances the probabilistic characterization and understanding of the behavior of a key groundwater parameter, the saturated hydraulic conductivity.Standard ANSI/ASCE/EWRI 65-17 provides guidelines for calculating saturated hydraulic conductivity (Ksat), permeability, and porosity of fine-grained soils. The calculation has four components: strain-stress data from a step-load test; one-dimensional vertical consolidation theory relatingKsatto the coefficient of consolidation; the relation betweenKsatand permeability; and the relation between porosity and the void ratio of the soil.This standard?s methodology can be applied to refine or improve calculations of land subsidence, groundwater flow prediction, and transport of dissolved solutes moving in groundwater. The methodology in this standard is limited to fine-grained, compressible, inorganic soils. Highly organic soils (peat) exhibit anomalous primary and secondary consolidation and are out of scope of this standard.Standard ASCE 65-17 will be useful to environmental engineers, water resources engineers, and anyone who uses hydraulics in engineering.
