摘　　要：针对软基堤坝易沉陷、滑移、倒塌、施工难、工期长等问题 ,提出了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 ,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 ,说明轻质硬壳堤坝比传统堤坝具有更高的可靠性 .Paying respect to the sinking, movement and collapse of the soft embankment itself,overweight and looseness are major factors on the stability of the dyke,so the light & hard-shell dyke(LHD) is presented. It can be built with highstress materials outside and loose materials inside. Several problems about cross-section design are to be solved according to statics characters,structure requirements,performance conditions and the requirement of anti-slid stability. Then based on computing and analysis for an instance,it is concluded that the LHD possessed more overall stability than traditional embankment.;
