干湿循环对高等级路基的影响

摘要

以某高等级路基为研究对象,通过三轴剪切试验和三轴渗透试验,研究了干湿循环作用对高等级路基的透水性、变形及强度的影响,并加以分析说明,为高等级路基长期稳定性评价提供了指导。%Taking some high-quality roadbed as the research objects,the paper researches the influence of the dry-wet cycle on the permeability,the deformation and the strength of the high-quality roadbed by the triaxial shear test and the permeability experiment under triaxial compressive,and undertakes the analysis and indication,so as to provide the direction for the long-term stability evaluation of the high-quality roadbed.
