Newly developed geotextile horizontal drains(abbreviated as GHDs)were introduced in reinforced soft clay embankments. GHDs consist of geosynthetic materials with reliably high transmissivity and core strength. The basic reinforcing characteristics of GHDs were investigated with a pull-out test and direct shear test. According to the test results, GHDs can be used for the reinforcement of soft clay embankments. A new design procedure was used for a calculation model including the GHDs, and the slope deformation and pore water pressure dessipation were estimated. The safety factors of the reinforced embankments using GHDs were esimated by steps of pore water pressure dissipation. The results clearly showed a good effect of the geotextile horizontal drains in the reinforcement of soft clay embankments.
