【Abstract】 Dynamic creep characteristics, fatigue life and fatigue failure mechanism for woven, needle-punched nonwovens and needle-punched composite geotextiles were tested and studied in this paper. The results show that the dynamic creep curves coincide with the power and logarithmic function. The dynamic creep characteristics and fatigue life of geotextiles are closely related to the constituent fibers performances, geotextile texture and cyclic load condition.更多还原
