There are many properties of geotextile, such as tensile strength, corrosion resistance and so on. But the creep property of geotextile is rarely heard. What is the creep of geotextile?

The creep of geotextile refers to the phenomenon that the geotextile increases with the extension of time under the action of constant external force, which we call creep. The creep property of geotextile is also one of the important indexes of geotextile, which has a great influence on the reinforcement function of geotextile.

What is the use of creep property of Geotextile

When geotextile is used for reinforcement on soft foundation, it will be subject to certain tension. If the creep performance of geotextile produced by geotextile manufacturer fails to reach the specified index, and it is subject to such tension for a long time, then it is easy for geotextile to be unable to restore to its original state due to deformation. Such geotextile will not only affect the stability of subgrade, but also may cause subgrade Local collapse.

If the geotextile on the dam breaks because it can't bear the tension, it is conceivable that the dam will probably collapse completely. Therefore, the creep behavior of geotextile is very important for its reinforcement.

Factors affecting creep of Geotextile

Speaking of the creep of geotextile, actually it is a very complex physical phenomenon, so there are many influencing factors. Here are a few simple examples:

1. Time: with the increase and extension of time, although the non creep strain rate of geotextile will decrease, there is no mistake that it is increasing all the time;

2. Types: different kinds of geotextiles have different creep properties, which are not only related to raw materials, but also to additives;

3. Organization: that is, the structure of geotextile, that is, the elongation of fiber in geotextile will affect the creep performance of geotextile, generally, the worse the elongation, the greater the creep performance;

4. Temperature: in other conditions, with the increase of temperature, the instantaneous creep and creep rate of geotextile will increase;

5. Load: the greater the load, the greater the tension on the geotextile, so the faster it will creep.

The above is about the function of creep property of geotextile and the introduction of influencing factors.
