土壤渗透性的测定是评估地上储罐设施二次密封区域的最重要项目之一。本出版物概述了测试土壤渗透性的各种方法，并区分了实验室方法和现场方法，但并未提供所有可用渗透性方法的详尽列表。这些方法是根据其对特定土壤类型的适用性确定的。本报告中介绍的方法适用于细粒土（粉土和粘土）和粗粒土（砂和砾石），但可能不适用于有机土，如泥炭，或建筑和拆除垃圾等材料。应全面调查所有方法的适当性，并确定其适用于特定情况

The determination of soil permeability is one of the most important items in assessing aboveground storage tank facilities' secondary containment areas. This publication outlines various methods to test the permeability of soil and distinguishes between laboratory and field methods, though it does not supply an exhaustive list of all available permeability methods. These methods are identified according to their applicability to particular soil types. The methods presented in this report are applicable to fine-grained soils (silts and clays) and coarse-grained soils (sands and gravels), but may not be appropriate to organic soils, such as peat, or to materials such as construction and demolition debris. All methods should be fully investigated for appropriateness and to determine its suitability to a particular situation
