一种新型筑堤结构──轻质硬壳堤坝
|
摘要
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。
in this paper, a novel structue of embankment, light dike, is presented in order to solve ground problems such as subsiding, slipping, displacement, and collapsingetc. Being adopted foam plastics as materials, it is paved above thd soft ground, of infilled in weak area. The dike can be built with highstress materials outside and loosematerials inside. So it has an effect of lightening weight, reinforcing, preventing seeping, separating and being piled up higher. Thus it enhances its stiffness and stability.This new structue of dike and dam has the high ability of solid--control and is aseismic.It also has other advantages such as shortening the constsuction period, reducing thecost of construction and utilizing waste materials.
