摘要
针对西咸北环高速公路路基填筑时利用了大量建筑垃圾,其中含有大量镉(Cd)和砷(As)等微量污染物的现状,利用Hydrus软件对建筑垃圾中Cd和As在路基中的迁移进行了模拟。模拟结果显示,20年内Cd和As的最大穿透深度不超过3cm和3.5cm,远高于该地区地下水位的埋深,不会对地下水造成污染。
A large amount of construction waste is used in the construction of the subgrade of Xi’an-Xianyang northloop expressway,which contains trace pollutants such as cadmium（Cd）and arsenic（As）.Using the Hydrus soft-ware,the migration of Cd and in the roadbed was simulated.The simulation results shown that the maximum penetra-tion depth of Cd and As in 20 years is not more than 3 cm and 3.5 cm,which is far higher than the underground waterlevel in the area,and does not cause pollution to the groundwater.
