摘要
通过试验观测和理论分析 ,春季灌区道路形成的翻浆现象是由于冬季土壤冻结时土中水分产生迁移 ,在路基下形成的聚冰层春季融化造成路基承载力降低 ,外作用下路基破坏 ,实质上它是一种冻害现象。据此提出解决道路翻浆危害的一些防治措施 :抬高路基 。
Through experiment, the phenomena on frost boil of roads in spring results from the forming of assembled ice layer under the road bed which water heads to during the soil's freezing in winter, from the roadbed bear strength declining due to ice's melting in spring and from the truck load.Therefore, it actually belongs to frost injury. Several measures such as enhancing the roadbed height, drainage as well as exchanging the roadbed maternal to resolve the harmfulness of frost boil of roads was proposed according to the analysis.
