摘要
针对吹填造陆工程中常见的粗细粒共存、砂含量分布不均的砂-黏土混合物,配制了7组不同含砂条件的试样,研究不同含砂条件对吹填土固结特性的影响。结果表明:含砂量的增多和砂粒径的增大均能提高混合土的压缩性,且增加含砂量对土体压缩性的提高效果略高于增大含砂粒径;含砂量的增多和砂粒粒径的增大均能提升砂-黏土混合物中土的透水能力,提高土体固结系数,加速土体固结。
According to the sand-clay mixture with coexisting coarse and fine particles and uneven distribution of sand content,7 sets of samples with different sand conditions were prepared to study the influence of different sand conditions on consolidation characteristics of blown fill soil.The results show that the increase of sand content and the increase of sand size can improve the compressibility of mixed soil,and the effect of increasing sand content on soil compressibility is slightly higher than that of increasing sand size;The increase of sand content and the increase of sand particle size can improve the permeability of soil in sand-clay mixture,improve the consolidation coefficient of soil and accelerate the consolidation of soil.
