| 摘 要： | 通过有限元软件ANSYS对土工格栅加筋路堤进行模拟，阐述了加筋土的加筋作用原理。通过一个工程实例分别对不加筋、仅加砂垫层、加一层土工格栅砂垫层、加两层土工格栅砂垫层四种不同的加筋路堤进行了计算。分析了不同加筋方式下加筋土路基竖向位移、侧向位移、竖向应力、剪应力和筋材拉力的规律。

| Abstract: | In this paper,geogrid reinforced embankment is simulated with the finite element software ANSYS, expound the role of reinforced soil reinforcement principle. Four different geogrid reinforced embankments included unreinforced embankment, sand cushion embankment, one layer of geogrid embankment , two layers of geogrid embankment are calculated with an engineering example. Analyse the impact of reinforced soil on subgrade＇s lateral displacement, vertical displacement, vertical stress, shear stress and tension of reinforcement under different reinforced methods. |
