加筋风积砂强度和变形特性的有限元分析

Studies on the performance of aeolian sand reinforced and deformation characteric by geogrids with FEA

针对风积砂土特殊的物理力学性质,应用弹塑性有限元法研究加筋风积砂的强度和变形特性,分析加筋机理,并采用土工格栅作为加筋材料对风积砂土进行加固,以提高土体的强度和稳定性。

According to the physical and mechanical speciality of reinforced aeolian sand and by the way of elasto-plasticiy FEA to study the reinforced aeolian sands strength and deformation performance, and adopt the geo-grid as the reinforcement material strength the sand soil that gathered by wind and increase the strength and stability of soil body, so as to improve the soil strength and stablity.
