摘要：

An in-situ installation survivability study was performed for the purpose of evaluating the amount and degree of installation damage of PVC-coated PET flexible geogrids placed in five types of commonly used backfill materials. The reduction factor for tensile strength due to installation damage is significantly related to soil type and varies from 1.01 to 1.74. The reduction factors for junction strength due to installation damage varies from 1.00 to 1.40 for different type of soils. Additionally, 2% of the maximum load is recommended as the preload for single rib tensile strength test (GRI-GG1). In comparison of the test results, wide width tensile strength (ASTM D4595) of the test geogrids is about 10% to 20% lower than those obtained from single rib tensile strength tests (GRI-GG1). The difference of tensile strength obtained from these two test methods increases as the construction damage effect increases.
