Abstract：Based on the creep experiments for geosynthetics under long-term load，the creep characteristics of Netlon CE131 geonet and their influencing factors are studied. The mechanism of occurrence，development and failure of creep fracture for Netlon CE131 geonet is studied too. Based on the experiments，the creep formula for the Netlon CE131 is obtained. When the exterior load is larger than 60% of the ultimate tensile strength and the temperature is higher than 25 ℃，the creep of Netlon CE131 is apparently affected by the change of the temperature. But it is no longer affected by the temperature when the stress level is below 40% or the temperature is lower than 25 ℃。
