摘要
为减少路基沉降,通常采用轻质填料填筑路堤,其中常用的填料有粉煤灰、土工泡沫塑料和泡沫轻质土.通过工程实例,介绍了这3种填料在路堤中的填筑方法,并结合不同路堤高度、不同填料的工后沉降量及工程造价,对工程设计方案进行了比选.
Abstract
Light fillers are usually used to fill the subgrade for reducing the settlement of subgrade.The common fillers are fly-ash,geofoam plastic and foamed lightweight soil.Through an engineering example,the filling methods of the three materials in the embankment are introduced.Combined with the post-construction settlements and engineering costs of the different embankment heights and the different fillers,the engineering design schemes are compared and selected.
