适用范围：This International Standard specifies the determination of the hydraulic conductivity of granular soils (e.g.sand and gravel) using a constant-head method involving a rigid-wall permeameter to measure the laminarflow of water. The procedure establishes representative values of the hydraulic conductivity of granular soilsthat can occur in natural deposits as placed in embankments, or when used as base courses underpavements.In order to limit consolidation influences during testing, this procedure is applicable only to disturbed granularsoils containing not more than 10 % soil passing a 75-μm sieve.This procedure is applicable to the measurement of hydraulic conductivity of compacted samples of sandsand gravels containing little or no silt, where flow along the rigid wall of the permeameter has no practicalimplications on the test results. This International Standard is not applicable to silt and clay, whereseepage/flow at the boundaries is not acceptable.
