摘要
利用有限元数值方法分析了软基上的堤坝,通过计算分析发现利用土工合成材料,可以约束软土的侧向变形,减少坝基沉降和不均匀沉降,同时可以使塑性区的面积明显减少,但是加筋的层数不宜太多.
The paper analyses the embankment on soft bed by finite element method, and through calculation and analysis it proposes that the use of geosynthertics can restrict the side distortion of soft earth, reduce the sedimentation and asymmetric sedimentation of embankment, and reduce the plastic areas obviously. But at the same time, the reinforced layers should be limited.
