Geotextile, as a multifunctional geosynthetic material, plays an indispensable role in various engineering fields. It is mainly made of synthetic fibers through processes such as needle punching or weaving, and has good filtration, drainage, isolation, reinforcement, and protection properties.
In road engineering, geotextiles are widely used for roadbed treatment and pavement reinforcement. Laying geotextile on soft soil foundation can utilize its reinforcing effect to enhance the bearing capacity of the foundation, disperse the load transmitted by the road surface, reduce the settlement and deformation of the roadbed, and extend the service life of the road. For example, in some newly built highway projects, laying geotextiles on soft soil foundation sections effectively avoids problems such as road cracking and potholes caused by foundation settlement, ensuring the smoothness of the road and driving safety.
In the field of hydraulic engineering, the application of geotextiles is extremely critical. In dam engineering, geotextile can be used for anti-seepage, filtration, and drainage. For example, in the construction of dams in reservoirs, laying geomembranes (a special type of geotextile) inside or on the surface of the dam can effectively prevent water leakage and ensure the reservoir’s water storage capacity. At the same time, the anti filtration function of geotextile can prevent soil particles from being lost with water flow, ensuring the stability of the dam. In channel anti-seepage engineering, the use of geotextiles can significantly reduce water leakage losses and improve irrigation efficiency.
Geotextiles also play an important role in the field of environmental engineering. At landfills, geotextiles are used to isolate garbage from surrounding soil, preventing harmful substances from infiltrating and contaminating groundwater and soil. At the same time, it can also cooperate with the drainage system to collect and guide the leachate from garbage for subsequent treatment. In tailings treatment, geotextile can also play a role in isolation and drainage, reducing the pollution of tailings to the environment.
In railway engineering, geotextile is often used between the track bed and the roadbed. It can effectively isolate the ballast from the roadbed soil, prevent the ballast from sinking into the roadbed, and maintain the stability of the track bed. At the same time, it also has drainage function, timely draining rainwater and groundwater to avoid the roadbed being soaked in water and reducing its strength.
In addition, geotextiles can be used in coastal protection projects to prevent coastal erosion. By laying geotextiles and combining them with other protective measures such as stone throwing, the coastline can be protected from wave erosion and the ecological balance of the coastal zone can be maintained.
In short, geotextiles provide strong guarantees for the smooth implementation and long-term stable operation of various projects with their unique properties and wide application fields. With the continuous development of material technology, the performance of geotextiles will continue to improve, and their application scope will also be further expanded.
