工业废渣改良过湿土路基稳定性研究

由于过湿土地区透水性差、粘性高、天然含水量大,因此如何解决过湿土的压实问题成为过湿土地区面临的重要难题。结合国家提倡建设绿色交通和生态公路的指导方针,利用工业废渣改良过湿土路基,解决了过湿段路基难以压实以及承载力低的问题。通过力学试验确立最佳配合比,并在此基础上验证了工业废渣改良过湿土的耐久性。

Study on Stability Improvement of Subgrade on Over-wet Soil with Industrial Waste

Due to the features of over-wet soil including weak permeability,high viscosity and large water content, the compaction of subgrade on over-wet soil has become a problem.Combined with the country's guideline on building green transportation and ecological highways,industrial waste was introduced to solve the compaction problem.The optimal mix proportion was determined by mechanical test,based on which the durability of over-wet soil improved by industrial waste was verified.
