Abstract: A portable multifunctional tester for pollutant erosion effect, including a base, the ejection head of jacking device is provided with a container. The upper end and lower end of the sample are provided with an upper porous stone and a lower porous stone respectively. A metal cover plate is disposed on the upper porous stone. An ejector rod with a circular tray is fixed to the support. The stress controlled one-dimensional load test can be performed by putting weights on the circular tray. A pressure gauge is disposed on the ejector rod. A displacement meter is disposed on the top cover plate. The container has a water inlet and a water outlet connected to its inner chamber. The water inlet, circulating pump, accumulator and water outlet are connected by conduits. In addition, a unidimensional consolidation test and washing test method thereof is provided.
