摘要
采用有限元方法对土工织物加固软土路基的效果和机理进行了探讨。计算得到了加筋前后路基内的竖向沉降、侧向位移、孔压变化及稳定性发展等,为工程实际中土工织物的合理应用提供参考。
The compatible state of deformation between geotextile and soil can not be reflected rightly with limiting equilibrium method. So, the effect of geotextile used in soft soil foundation is studied with linear finite element method （FEM） in this paper. The vertical settlement, the lateral displacement, distribution of excess pore pressure and stability of reinforce-embankment are got with FEM. In a certain degree, the results can help using geotextile reasonably in practice.
