Tough expansive soil roadbed structure based on nano silicon dioxide and carbon fibers
The invention provides a tough expansive soil roadbed structure based on nano silicon dioxide and carbon fibers, and belongs to the field of geotechnical engineering. The tough expansive soil roadbed structure comprises an expansive soil filling core, a roadbed top edge covering layer, a roadbed bottom edge covering layer and two roadbed side slope edge covering layers, and the expansive soil filling core is arranged in a closed space defined by the four edge covering layers. The laying material of the four edge covering layers is modified expansive soil and is formed by uniformly mixing a modifier, water, carbon fibers and site expansive soil, and the modifier is prepared by mixing hydrophobic nano silicon dioxide and lime. The expansive soil roadbed is filled by using a modified expansive soil edge covering method, and the method has the advantages of being wide in applicability, capable of remarkably shortening the construction period, high in edge covering layer strength, low in permeability, low in expansibility and good in durability.
本发明提供了一种基于纳米二氧化硅与碳纤维的韧性膨胀土路基结构，属于岩土工程领域。所述韧性膨胀土路基结构包括膨胀土填芯、路基顶部包边层、路基底部包边层和两个路基边坡包边层，所述膨胀土填芯设置在四个包边层所包围的封闭空间之中。所述四个包边层的铺设材料均为改性膨胀土，由改性剂、水、碳纤维、场地膨胀土均匀混合而成，所述改性剂为疏水性纳米二氧化硅与石灰混合制作而成。本发明采用改性膨胀土包边方法填筑膨胀土路基，具有适用性广，显著缩短施工工期，包边层强度高、渗透性低、膨胀性低、耐久性好的特点。
