A study on development for separation and reinforcement geotextiles with horizontal drain property

According to the recent civil engineering construction work site which is a complex pro-cess, development of multi-functional geotextiles is required. In this study, the characteristics of five dif-ferent modified cross-section fiber yarns for the selection of wicking yarns were analyzed and yarns that can achieve target properties were selected. Experimental prototype geotextiles suitable for horizontal wicking drain property and reinforcement was developed and its tensile strength, 2% secant modulus, ver-tical water permeability, AOS, friction characteristics by the direct shear method, and vertical/horizontal wicking test were analyzed. These tests are conducted to verify the performance of the geotextile with horizontal wick drain property, separation and reinforcement developed in this study.
