摘　　要：针对软基堤坝易沉陷、滑移、倒塌的问题 ,提出一种新型的筑堤结构。该结构采用高强度材料作为外壳 ,以轻质材料放置于易沉滑的部位 ,以松散材料填充坝体。根据受力特性、构造要求、施工条件及抗滑稳定条件 ,拟解决结构断面设计的一些基本问题 ,并结合实例运用专业程序进行了对比计算分析 。A new type light & hard-shell dyke (LHD) is presented with respect to the sinking, movement and collapse of the soft embankment itself. This structure uses the high strength material as its shell, the light material is positioned in the place easily sinking and sliding, and the loose material is filled in the body of the embankment. According to the statics characters, structure requirement, construction condition and the requirement of anti-slid and stability, several issues about cross-section design are solved. Combined with the concrete instance, applying to the specialty program and having the comparing calculation analysis, it is concluded that the LHD has much more stability than traditional embankment.
