| Title of the article | Characteristics of the interaction of geosynthetic material with sandy soil during pulling tests |
| Abstract. | Problem statement. Soil reinforcement is widely used in modern construction. In the course of designing geotechnical structures made of soil reinforced with geosynthetic materials it is necessary to quantify the interaction of the reinforcement elements with the soil. Such interaction is characterized by contact characteristics, namely the friction angle and adhesion at the contact of the geosynthetic material with the soil. Today, the interaction characteristics are in most cases accepted according to tables and recommendations of regulatory documents. In the Russian Federation, the engagement of interaction characteristics obtained during laboratory tests is not applied in practice despite the fact that the national standard is in force, and the methodology and requirements for equipment for conducting laboratory tests to determine these characteristics are set out in it. The purpose of the work is to study the contact characteristics obtained during the tests on geosynthetic material pulling from the soil according to the regulatory documentation. The completed work includes: design and manufacture of a plant for testing the geosynthetic pulling from the soil; determination of the characteristics of geosynthetic material pulling from the soil; analysis of the obtained results; study of the mechanism of operation of the reinforcing geosynthetic element in the soil during the pulling process. Results. The article presents the results of tests on pulling the woven geosynthetic material out of sandy soil according to the method of the national standard. The values of the friction coefficients adopted according to the recommendations of regulatory documents exceed the results of the experimental values obtained during the present studies by 40-70%. In the process of pulling out three characteristic stages of reinforcement behavior have been recorded and thoroughly described. Based on the results of the conducted research, recommendations for conducting tests on pulling of woven geosynthetic material have been formulated. Conclusions. The results of the study play an important role in the design and calculation of reinforced soil structures. The contact characteristics of the interaction of soil with the reinforcing material of reinforcement, obtained during tests for pulling geosynthetic material out of the soil, contribute to increasing the reliability, safety and economic efficiency of such structures. |
