Soil permeability tests require a time series of water level measurements to determine system losses, including both infiltration and evaporation. Laboratory measurements of flow are standardised by international regulations such as ASTM International, ISO or UNE, but field measurements are not as well described and in some cases may require definition and specification of test conditions. This is the case for geosynthetic clay liner (GCL) products, where permeability is assessed by a laboratory measurement using a flexible wall permeameter as defined in standard test method D 5887-04. This method is not able to evaluate the performance of such products in the field and therefore cannot guarantee their ability to be used for the repair of landfill liner overlays. For this reason, we have defined a field test in a confined steel ring and developed a real-time ultrasonic IoT device to evaluate water losses over a period of time. The test method was applied in Mallorca (Spain) and as a result the quality of a landfill cover repair solution was evaluated, the corresponding civil works were carried out and the basis for future field measurements of soil permeability tests on different materials and conditions was established.
土壤渗透性测试需要一系列水位测量数据来确定系统损耗，包括渗透和蒸发。流量的实验室测量按照国际法规（如美国材料与试验协会国际组织、国际标准化组织或西班牙标准化与认证协会）进行标准化，但现场测量的描述不够完善，在某些情况下可能需要对测试条件进行定义和规范。土工合成粘土衬垫（GCL）产品就是这种情况，其渗透性通过使用标准测试方法D 5887-04中定义的柔性壁渗透仪进行实验室测量来评估。这种方法无法评估此类产品在现场的性能，因此无法保证其用于填埋场衬垫覆盖层修复的能力。出于这个原因，我们在一个密闭钢环中定义了一种现场测试，并开发了一种实时超声波物联网设备来评估一段时间内的水分损失。该测试方法在西班牙马略卡岛得到应用，结果评估了一种填埋场覆盖层修复解决方案的质量，进行了相应的土建工程，并为未来在不同材料和条件下进行土壤渗透性测试的现场测量奠定了基础。
