【摘要】 从海堤本身角度看 ,坝体过重与填料松散是影响其稳定性的主要因素 ,因此轻质硬壳堤坝是一种很好的选择。该结构采用高强度材料作为外壳 ,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 ,并结合实例通过对比计算分析 ,说明轻质硬壳海堤比传统海堤具有更高的整体稳定性。更多还原

【Abstract】 In terms of the embankment itself, overweight and looseness are major factors on the stability of the dyke, so the light core and hard shell dyke(LHD) is presented. It can be built with high strength materials outside and loose materials inside. Several problems about the cross section desigh are to be solved hased on static characters, structure requirements, performance conditions and the requirement of anti slide stability. Then based on computation and analyses of an actual case, it is concluded that the LHD possesses more overall stability than the traditional embankment.更多还原
