摘要
在黄土地区修建高等级公路,常因路基顶面积水而影响路基使用性能,严重时会影响公路的正常使用。本课题基于黄土路基压实后土体的基本性质,通过室内一维土柱入渗试验,利用γ射线法对不同压实度下黄土积水入渗状况下的水分分布进行测试研究,得出相应的黄土路基积水入渗规律,为黄土路基综合排水设计提供重要的理论依据。
For high type highway in loess area,water log on subgrade top often influences the highway in service performance,sometimes it seriously influences normal use of highway.Based on the basic test of the compacted fill (loess subgrade has been compacted),this paper presents the indoor one dimensional soil column infiltration test by using γ ray method to study the moisture distribution of loess water log under different compaction degree,with the suitable loess subgrade water log infiltration pattern having been obtained,providing important theoretical basis for comprehensive drainage design.
