Geotextiles can also be used to separate different types of rock and soil geotextile produced divided into two categories according to their causes, ie load and non-load crack crack. There are loads of fatigue crack damage caused traffic load generated by the non-load crack usually changes in temperature and humidity as well as due to the characteristics of the material itself, there are some cracks are caused due to differential settlement of subgrade. This is mainly semi-rigid base is formed by compacting the latest short silk geotextile under optimum moisture content of the state, with the passage of time and changes in external conditions, when the material itself can not resist tensile stress changes caused by the outside world When the stress cracking phenomenon is generated. Geotextiles can also be used to separate different types of rocks and soil, as well as reinforcement. Like a dike or berm project, work is in progress in a short silk geotextile wholesale, or may decline in bad weather trends in soil and rocks. We can use geotextiles for protection of embankments and slope. It can be fixed together with plant roots slope, providing stable protection. In some applications, geotextiles may be for health and safety in the environment being used practical staple fiber geotextiles, such as environmental authorities want to prevent soil erosion by water. Geotextiles can also be used to inhibit weed growth and help protect the environment, and other foundations. According to Dawa and the Hun River embankment slope soil test results, Cheung indoor filtration analysis drawn by A. Curve shown in Figure. According to the different experimental conditions mutated geomembrane Richard critical curve points (destruction) gradient table. From the test results, the selected good anti-clogging performance geotextiles short silk geotextiles, especially Dawa soil. Whether in standard or non-standard tests Huai, Dawa soil Cheung cR values ??are less than o. 8, Andrew Dawa standard soil test, Alexandra value even less than o. 5. Substantially equal to o. 44. Only the largest case of non-standard o. 76, but with the increase in head even decreased, indicating the role of head of the higher filtration geomembrane play better. Hun River soil samples were used geomembrane filtration effects, although not as good at Dawa soil samples, but also within the range allowed by the specification (cA'3), is also the head of the higher, the better the filtration effect play. That is woven with a larger pore size is very small, as the likelihood of clogging of the filter layer. As can be seen from the figure the geomembrane, in the case where the hydraulic gradient is less than 73, the permeability coefficient and flow velocity are not mutated, flow rate and water head under various conditions geomembrane substantially maintained a relatively slow proportional growth of eels. Critical protective case (the damage) was significantly higher than those without the protection of slope, in line with the actual project situation. There are two conditions under the protection of r. Point mutations i f curve is greater than 95, the protection of gravel i value greater than 100, which is equivalent to a 95- 100m head in 1M thick filter layer seepage path. Geomembrane revetment works on flood control is almost impossible, in fact, it is sufficient to meet the project by 50 security needs. So geomembrane show by experimental analysis of indoor filtration geotextile om poison 10J9 Soil new guidelines for insurance protection engineering filtration designed with adequate margin of safety.
