The key role and application advantages of geotextiles in the anti-slip performance of embankments

In embankment projects, landslides are usually caused by soil movement caused by weak foundations, high groundwater levels, excessive rainfall or external forces. The high tensile strength, permeability and deformation resistance of geotextile give them obvious advantages in improving the anti-slip performance of embankments. Specifically, they are manifested in the following aspects:

Enhanced tensile strength: Geotextiles have high tensile strength, which can effectively disperse the load of the upper structure of the embankment and evenly transfer stress to the lower soil to avoid slippage caused by local uneven force. Especially under high water levels or soft soil conditions, the application of geotextiles can enhance the overall stiffness of the embankment structure and improve its anti-slip ability.

Drainage function: The occurrence of landslides is often accompanied by the accumulation of water in the roadbed soil, especially in rainy areas or places with high groundwater levels. Water retention will lead to a decrease in soil bearing capacity and induce landslides. The good water permeability of geotextile can effectively remove excess water inside the soil, lower the groundwater level, reduce the destructive effect of water pressure on the embankment, and thus reduce the risk of landslides.

Improve the deformation resistance of soil: Geotextile can enhance the deformation resistance of soil. By applying additional constraints to the soil, it is less likely to undergo large-scale deformation and slippage under the action of external forces, further improving the stability of the embankment.

According to the geotextile product information you provided, the product has the following key features, which play a vital role in the anti-slip performance of the embankment:

High water permeability and water conductivity: In embankment construction, the accumulation of water inside the soil is a common factor that induces landslides. By using geotextiles with good water permeability, drainage channels can be effectively formed to discharge excess water from the soil, reduce the damage of water to the stability of the soil, and reduce the probability of landslides.

Corrosion resistance and long-term durability: Geotextile products use polypropylene or polyester chemical fiber as the main raw material, and have the characteristics of acid and alkali resistance, non-corrosion, insect resistance and oxidation resistance. This enables it to maintain a long service life in various complex natural environments, providing reliable protection for long-term embankment anti-slip.

Good tensile strength and anti-deformation performance: The tensile strength and anti-deformation ability of geotextiles enable it to effectively prevent the soil from sliding under heavy loads or external forces during embankment construction, thereby improving the anti-slip ability of the embankment and enhancing the stability of the overall structure.

The application of geotextiles in the anti-slip performance of embankments not only improves the safety and reliability of the project, but also brings significant economic benefits:

Save construction costs: Compared with traditional reinforcement materials such as stone or concrete, the use of geotextiles greatly reduces the material cost and labor cost in construction. Its light weight and easy laying characteristics make the construction process simpler and more efficient, especially suitable for use in large-scale embankment projects.

Reduce post-maintenance: The durability and anti-corrosion performance of geotextiles significantly extend the service life of embankments and reduce the frequency and cost of post-maintenance. Due to its good drainage and anti-slip functions, it can effectively slow down the occurrence of disasters such as landslides, thereby reducing the cost of embankment repair.

Environmental friendliness: Geotextile materials are non-toxic and harmless, and will not pollute the environment. As environmental protection requirements become increasingly stringent, geotextiles, as an environmentally friendly building material, fully meet the standards of green engineering construction, further enhancing their application value in embankment projects.
