Tensile properties of woven geotextiles used as silt fence protectors were interpreted in accordance with design parameters, tensile strength values of float and curtain parts, service periods, and safety factors, etc. Resistance force of the float part increased with wind velocity and that of the curtain part increased with tide and sea water velocity. Total tensile strength of woven geotetiels and that of the float part increased with resistance force. Bending angle of the silt fence protector decreased with greater tensile strength of woven geotextile when the length of curtain part and diameter of float part are constant. For longer service periods and higher safety factor, design strength of woven geotextile must be calculated considering the total external forces such as resistance force of the float part and tensile strength values of the curtain part.
