In the port and waterway engineering,the permeability coefficient of soil is an important design index,which is of great significance in practical engineering.At present,the widely used test methods of permeability coefficient have limitations,the intelligent,accuracy,operability and environmental adaptability need to be improved.To solve this problem,we develop a set of shipboard multifunctional permeameter,and test and compare the application of this permeameter on a marine geological survey project in Caofeidian.The results show that the permeameter can not only suitable for ship shaking environment,but also can measure permeability coefficient under the condition of simulating in-situ stress state of soil in laboratory by adopting automatic and intelligent design.The shipboard multifunctional permeameter is convenient to operate,high degree of accuracy and automation,and the coefficient of soil pressure at rest can be measured by changing test method.
