One of the main functions of geotextiles in embankment engineering is to improve the overall stability of the embankment structure through its high tensile strength. In embankment construction, the foundation soil is often affected by external forces such as vehicle loads, climate change, and earthquakes, which can easily cause soil deformation and slippage. The high tensile strength of geotextiles can effectively disperse and transmit these external forces, thereby improving the deformation resistance of the embankment structure. Specifically, it is manifested as follows:
Stress dispersion: When external forces act on the embankment, geotextiles can quickly disperse the stress concentrated in the local area to a larger range, avoiding slippage and settlement caused by excessive local soil load, thereby improving the stability of the overall structure.
Reduce roadbed settlement: Geotextiles with high tensile strength play a basic supporting role in the laying of the bottom layer of the embankment, which can effectively suppress the problem of uneven settlement of the roadbed.
Enhance the soil's ability to resist deformation: Under the conditions of soft foundation or high groundwater level, the soil is often prone to deformation, causing instability of the embankment. Geotextiles exert constraints on the soil through their high tensile strength, enabling it to reduce deformation when subjected to external forces and enhance the deformation resistance of the embankment.
According to the product information you provided, the geotextile has tensile strength and other key properties, such as good water permeability, corrosion resistance and high durability. These characteristics play a vital role in enhancing the tensile strength of the embankment structure:
High tensile strength: The tensile properties of geotextiles enable it to withstand large external forces in embankment reinforcement without breaking or excessive deformation.
Corrosion resistance and long-term durability: Geotextiles made of polypropylene or polyester chemical fiber as the main raw materials have good acid and alkali resistance, corrosion resistance, and oxidation resistance, and can be used for a long time in various harsh natural environments without affecting its tensile properties.
Permeability and drainage capacity: Geotextiles not only have high tensile strength, but their water permeability can also form drainage channels inside the soil to prevent groundwater retention. The accumulation of groundwater often leads to soil softening, thereby reducing the tensile strength of the soil.
The advantages of geotextiles in enhancing the tensile strength of embankments are not only reflected in their mechanical properties, but also in terms of engineering costs and construction convenience. They show significant economic and construction benefits:
Reduced construction costs: Compared with traditional steel or concrete reinforcement methods, the use of geotextiles can significantly reduce engineering material costs and construction time. Geotextiles are light and easy to lay, and can quickly cover large areas of embankments while reducing damage to the surrounding terrain.
Improved construction efficiency: The construction process of geotextiles is simple and fast, without the need for complex mechanical equipment and a large amount of manual operation. Its flexible laying method enables the progress of the project to be greatly improved, especially in large-scale embankment reinforcement projects, the application of geotextiles can significantly shorten the construction period.
Environmentally friendly materials: Geotextile materials themselves are non-toxic and harmless to the environment, and will not pollute the surrounding soil or water sources. In engineering projects with increasingly stringent environmental protection requirements, the environmental protection characteristics of geotextiles make them an important choice to meet the needs of green engineering.
