Abstract In this study, the contribution of single and multiple layers of geogrids to bearing capacity and stress behavior was determined by laboratory experiments. The effects of parameters such as the depth of the first geogrid, the vertical spacing between the geogrid layers and the number of geogrid layers on the bearing capacity and settlement behavior of soil and stress distribution on geogrid and pipe by using strain gauges have been investigated. The results of experiments were given in dimensionless form of bearing capacity ratio (BCR), settlement reduction factor (SRF) and stress capacity ratio (SCR). As a result of experiments, the contribution of the geogrid on the soil-structure-pipe interaction has been observed together with the stress distribution on the geogrid contributed to the efficient use of the appropriate geogrid capacity.

土工格栅加固对土-结构-管相互作用在承载力、沉降和应力分布方面的影响

摘要 在这项研究中，单层和多层土工格栅对承载力和应力行为的贡献是通过实验室实验确定的。利用应变片研究了土工格栅的第一层深度、土工格栅层间的垂直间距和土工格栅层数等参数对土壤承载力和沉降行为以及土工格栅和管道应力分布的影响。试验结果以无量纲形式给出了承载力比（BCR）、沉降折减系数（SRF）和应力承载比（SCR）。作为实验的结果，土工格栅对土壤-结构-管道相互作用的贡献已被观察到，土工格栅上的应力分布有助于有效利用适当的土工格栅容量。
