针对软弱地基存在的堤坝不均匀沉降、滑坡、位移、倒塌等问题，提出了一种新型的筑堤结构──轻质硬壳堤坝。该结构采用发泡塑料作为堤坝材料，或铺设于软基面上，或填充于易沉陷部位，或搅拌于土石方中；以高强度材料，制成堤坝外壳或堤坝某一部分的外壳，然后填入其他松散材料，使其产生减重、加筋、防渗、隔离、堆高的作用，以增强堤坝刚度，提高堤坝稳定性。这种新型堤坝结构具有较高的防洪、抗地震能力，以及缩短建筑工期，降低造价，废物利用等优点。
Aiming at the problems of uneven settlement, landslide, displacement and collapse of levee in soft foundation, a new type of embankment - lightweight hard-shell dyke is proposed. The structure is made of foamed plastic as dyke material or laid on soft ground or filled in easily sinking parts or agitated in soil and earthwork. The high strength material is used to make the shell of a dam shell or a part of a dam, and then filled in Other loose materials, so that it produces weight loss, reinforcement, seepage, isolation, heap high role in order to enhance the dam stiffness and improve dam stability. The new dam structure has high flood control, anti-seismic capacity, as well as shorten the construction period, reduce costs, waste utilization and so on.
