... together with a summary of geotextile filter design principles and practices. A series of stress–pore-pressure-coupled finite-element (FE) analyses were then carried out on a number of tunnel cases in order to investigate the effect of hydraulic deterioration of the tunnel drainage layer on the structural...

... developed. The proposed analytical model consists of Stokes' and Gibbs' particle-settling-velocity equations in evaluating the time-dependent soil cake formation upstream of the geotextile filter. Analytical results show good agreement of the predicted effluent rates with those observed in a series...
