Evaluation of hydraulic conductivity for both marine and deltaic deposits based on piezocone testing

摘要: Abstract In order to rapidly determine the hydraulic conductivity for both marine and deltaic deposits in field, an approach is proposed evaluate of soil using cone penetration tests with pore water pressure measurement, known as piezocone testing. This based on test results from a series laboratory investigating expansion shape model tip different angles considering influence characteristics. To derive calculation method, two assumptions are made: i ) flow surface assumed be half ellipsoid shape, covering whole cone, ii initial state induced excess have negative exponential distribution dissipate surface. The compared existing data All three methods were applied analyze field cases, which cases deposit one deposit. show that can predict on-land deposit, extends range application approaches by Chai et al.
