Application of fibres for the stabilisation of steep slopes
For many years, techniques improving weak soils by means of additional elements incorporated into their structures have been applying in geotechnical structures (earth structures). An example of such a procedure is the use of geosynthetics enabling to solve geotechnical problems related to anti-erosion protection, as well as filtration and draining. In addition to geosynthetics, randomly distributed fibers are used. Fibers mixed with soil perform a function similar to the function of the root system of protective vegetation and enable the creation of flexible and easy to green construction. During the research, the influence of the type of fibers and their amount on erosion of slope located in the suburbs of Bielsko-Biala (Poland) was determined. Soil parameters and fiber properties were determined before their placement. Research on the physical properties of the soils and fibers morphological structure and strength was carried out in accordance with applicable standards. Subsequently, the slope stability was assessed during many months of exploitation. During the research, 2 m wide plots were created on the slope, covered with soil mixed with various amount of fibers. Fibers mixed with soil form a spatial grid retaining soil particles washed out by streams of surface water flowing down, limit the negative impact of erosion and increase slope stability. Natural fibers store excess water in soil, which promotes the development of protective vegetation.
