土工格栅在公路和铁路工程中应用广泛,但加筋结构中土工格栅效用的发挥仍不明晰。针对土工格栅受力状况测试的现状,提出采用电感式土工格栅位移计测量加筋结构中土工格栅应变的新技术,并在室内模型试验及现场土工格栅加筋路基试验段进行应用,通过电感式位移计测量的土工格栅应变与传统应变片测试结果及数值计算结果的对比,表明电感式土工格栅位移计测试技术准确可靠,适用于土工格栅加筋结构的现场测试。
Geogrids are widely used in highway and railway engineering, but the utility of geogrids in reinforced structures remains unclear. Aiming at the status quo of geogrid stress test, a new technique to measure geogrid strain in stiffened structure by inductive geogrid displacement meter is proposed and applied in indoor model test and on-site geogrid-reinforced embankment test section The comparison between geogrid strain measured by inductive displacement meter and traditional strain gauge test results and numerical results shows that the inductive geogrid displacement meter test technology is accurate and reliable and can be applied to field test of geogrid reinforced structure.
