| 摘 要： | 在进行堤防加筋设计时，土工织物的强度，加筋的长度，加筋的位置，加筋的层数等因素都是应该考虑的。利用欧洲通用的岩土工程有限元软件Plaxis，采用强度参数降低法，对某一堤防加筋的效果、机理作了分析。指出无论在任何位置加筋，土工织物都有一个最小长度。最小长度的确定，要具体问题具体分析。确定了加筋的最佳位置，并建议加两层，一层在底部，一层在中部，以抑制最危险滑弧的发展，提高整体稳定性，减少堤防变形发展。

| Abstract: | The strength, length, location in dike and layers of geotextile etc. have to be taken into accounted during the reinforcement design of dike. A finite element method with strength parameters reduction technique is introduced. By employing the Plaxis code, the geotextile reinforcement analysis for a dike is conducted; and the length of the geotextile reinforcement and the location of the geotextile reinforcement design are discussed. A suggested design method is given. |
