Abstract

The long-term performance of the reinforced material is an important factor affecting the safety, stability and economic rationality of the reinforced structure, as well as an important design parameter of the reinforced structure, which is affected by the construction damage, creep, aging and other factors during the construction and use of the reinforced material.In order to determine the long-term strength of reinforcement in the use of gravel reinforced structure, three kinds of reinforcement, HDPE, PET and PEC, were selected to carry out field full-size construction damage test and indoor tensile, creep and durability and other basic characteristics tests, and the following conclusions were obtained: (1) The protective layer of medium coarse sand with a thickness of 5cm can effectively reduce the construction damage of the reinforcement in the crushed stone. (2) The comprehensive reduction coefficients of PET180, HPDE150 and PEC200 without protective layer are about 2.60, 3.47 and 3.15, which can be reduced by about 7.0% after the protective layer is set. (3) The design strength calculated by nominal tensile strength and measured coefficient is safe, and the safety margin is about 1.06. (4) Compared with PET and PEC, the test parameters of strength and elongation of high-density polyethylene HPDE are more stable. The research results can provide a reference for the design of the reinforced material of the gravel reinforced structure.
