Abstract

The durability of geogrid reinforcement exhumed after 25 years from a sloped wall structure was examined through a comparison of the material properties of exhumed samples with technical data for the original product type. Visual and microscopic inspections found no evidence of installation damage. Analysis of strain increments in rapid loading creep tests to 10 000 h showed excellent agreement between the exhumed and original materials. The results of this study lend confidence in the use of isochronous load–strain–time data for predicting the long-term strain of geosynthetic-reinforced soil structures in design to a serviceability limit state.

斜面加筋土墙土工格栅服役25年后耐久性分析

通过将挖掘出的样品的材料特性与原始产品类型的技术数据进行比较，研究了25年后从倾斜墙结构中挖掘出的土工格栅加固的耐久性。目视和显微镜检查未发现安装损坏的证据。快速加载蠕变试验的应变增量分析表明，挖掘出的材料与原始材料之间具有良好的一致性。本研究的结果为使用等时荷载-应变-时间数据来预测土工合成加筋土结构在设计到使用极限状态时的长期应变提供了信心。
