Preliminary sedimentation experiments were conducted to compare the dewatering performance of different flocculants, and SAP was identified as the most effective additive for enhancing sedimentation. Laboratory vacuum preloading model tests were conducted on dredged clay treated with SAP and prefabricated vertical drain (PVD), to evaluate the effectiveness of SAP in enhancing the dewatering process. Results show that SAP enhances vacuum efficiency, leading to higher and faster vacuum pressure stabilization near the PVD. SAP-treated samples exhibited more rapid pore water pressure dissipation and accelerated water content reduction, particularly in the early stages. Post-treatment water content increased with distance from the PVD, but SAP improved overall drainage uniformity. Vane shear strength decreased with distance from the PVD but remained higher in SAP-treated samples, showing a linear correlation with normalized water content. SAP also influenced soil column formation, expanding its effective radius and reducing stabilization time. Two quantitative models were developed to predict shear strength and soil column radius variations under vacuum preloading with and without SAP. The radius of the soil column formed during vacuum preloading varied with depth, decreasing towards the bottom and increasing towards the surface.

This new composite integrates wicking capabilities with reinforcement. Unlike wicking woven geotextiles (WWGs), which rely on deep-grooved fibers for wetting and wicking, the wicking mechanism of WNWGs is primarily based on the microstructure and unique fiber orientation of the nonwoven geotextile component, further enhanced by proprietary chemical treatment to convert the fibers from hydrophobic to hydrophilic. This modification allows WNWGs to exhibit rapid wetting and wicking properties while preserving the large lateral drainage functionality of conventional nonwoven geotextiles. To assess the wicking performance of this material, a series of wicking tests were conducted in both water and saturated soils under controlled temperature and relative humidity. Additionally, contact angle measurements and microscopic analyses using Scanning Electron Microscopy (SEM) were conducted to elucidate the underlying wicking mechanisms.
