土工织物加筋机理的研究

Study on Reinforcing Mechanism of Geotextile

从土工织物加筋挡墙的离心模型试验，有限元法分析以及实际工程运用三个方面来研究其加筋机理；用有限元法对试验模型进行了分析研究，并将墙顶沉降，墙面侧位移以及土工织物上最大拉力点连线的试验和计算结果进行了对比，从而检验了计算中的假设；工程实例分析，所得结果与实测结果较吻合。

This paper studies the reinforcing mechanism of geotextile with the aid of centrifugal modelling test and FEM as well as practical application of geotextile to reinforced retaining walls. The test model has been analysed by FEM; the calculated results of settlement at the top of the retaining wall, the lateral displacement along the wall face and the line connecting the points of the maximun tensile force on geotextile have been compared with the test data, thus supposition in calculation has been examined. Analysis of a project has been done, and the reinforcing mechanism of geotextile has been further studied.
