摘要
针对国内对土工格栅铺设损伤的研究所得出的多是一些定性结论,缺乏定量结论的问题,展开了土工格栅强度损伤特性的试验研究.通过对应用于公路路堤加筋的工程条件下的4种不同类型、不同原材料的土工格栅的铺设损伤模拟试验,得到了在5种典型路堤填料下的几种典型土工格栅的强度损伤特性,并给出了相应的土工格栅铺设损伤强度折减系数的建议值.
Today the research of installation damage to geogrid is preliminary with qualitative results. However the quantitative results are not available. The simulation test has been performed to evaluate the installation damage of geogrid used in highway embankment reinforcement project according to different maximum grain size of fills, and the damage rules of of geogrid are obtained. Based on the results, the installation damage reduction factors for ultimate limit state design are given.
