Abstract

[In this work, creep of coated polyester yarn and leno-weave-based geogrid are studied. The results obtained showed a similar character of the dependence of the creep rate on the value of the level of the applied load between the deformation behavior of the polyester yarn and the geogrid. Further, based on the results of the yarn testing, a creep reduction factor was determined, which allows predicting the long-term strength of the polyester geogrid during its operation in geotechnical structures. In addition, this reduction factor was also obtained from creep rupture test of a polyester yarn. The data obtained were very close. As a practical application, the embankment over soft soil was calculated considering the creep reduction factor. It is shown that this methodology can significantly save building materials and time for construction work and thereby make a significant contribution to the use of energy-efficient solutions using geosynthetics.]
