%X Traditional oedometer was improved due to its shortage (permeability test can't be carried out on it). After improvement, the consolidation tests and permeability tests can be successively carried out to study the permeability characterics of the soil specimen under different loads. By controlling the drainage through a three-way valve, both double drainage test and single drainage test can be conducted, and not only pore water pressure at the bottom of soil specimen can be measured, but also pore water pressure on the different section can be measured respectively by the inter-connected consolidation apparatus. The improved apparatus has some merits, such as simple conformation and good watertight behavior. Comparing with traditional consolidation test and permeability test, its application to some tests gives more reasonable results. In addition, a phenomenon was found by he single drainage test, that the pore pressure from the bottom of specimen often delays.
