short fiber geotextile is a geotextile made of synthetic materials such as polyester or polypropylene, and its surface is covered with short filament-like fibers. This geotechnical material is often used to prevent soil erosion and collapse, effectively protect land resources, and maintain the ecological environment.

Soil erosion and collapse are issues that seriously affect land use and the ecological environment. Soil erosion refers to the erosion of the soil surface by factors such as wind, water, human activities, etc., resulting in a decrease in soil quality and fertility, and a loss of land productivity. Collapse is a collapse phenomenon caused by instability on the land surface or underground, which will threaten the safe use of land. The application of short fiber geotextiles can solve these problems to some extent.

First, short fiber geotextiles can effectively prevent soil erosion. Soil erosion is generally caused by natural factors such as wind and rain, and short-fiber geotextile can slow down the impact and erosion of wind and rain on the soil by fixing the structure of soil particles. The short fiber geotextile will be covered on the soil surface during construction. In the case of wind and rain erosion, the short fiber geotextile can effectively prevent soil loss. At the same time, short-fiber geotextiles can also prevent water from flowing too fast, thereby reducing water erosion of the soil. In this way, short-fiber geotextiles can effectively maintain the structure and fertility of the soil and reduce losses caused by soil erosion.

Secondly, short fiber geotextiles can effectively prevent soil collapse. The collapse of soil is mainly caused by structural instability within the soil, and short fiber geotextile can prevent collapse by increasing the stability of the soil. Short fiber geotextile has high tensile strength and shear strength, which can effectively fix soil particles. It can be laid on the surface of the soil or buried in the soil, effectively connecting soil particles together to form a stable soil mass. This stability enhances the soil's overall strength and prevents it from collapsing.

In addition, short fiber geotextiles also have other additional functions. It can provide a certain degree of water permeability, allowing water to quickly penetrate into the soil, keeping the soil moderately moist. At the same time, because the short fiber geotextile is made of synthetic materials, it has good corrosion resistance and aging resistance, and can maintain long-term stable performance under the influence of the external environment. In addition, short fiber geotextiles can also play a role in isolation and diversion, preventing impurities and solid objects in the soil from entering the water body, and protecting the cleanliness of water sources.

In general, short fiber geotextiles can effectively prevent soil erosion and collapse, which is of great significance for protecting soil resources and maintaining the ecological environment. However, it should be noted that the application of short-fiber geotextiles alone cannot completely solve the problems of soil erosion and collapse, and other soil protection measures and ecological restoration measures need to be combined to jointly deal with these problems. Only by comprehensively and scientifically applying geotechnical materials can better prevention and control results be achieved.
