Abstract To effectively improve the poor engineering properties of loess and
enhance its seismic performance, the industrial by-product lignin is used as a
modified material. Based on lots of dynamic triaxial tests, the dynamic elastic
modulus and damping ratio of lignin-modified loess were tested. The effects of
lignin content on the dynamic elastic modulus and damping ratio of lignin-modified loess were analyzed. Combined with scanning electron microscopy (SEM)
and X-ray diffraction (XRD), the microscopic mechanism of lignin to improve
the dynamic properties of loess was studied. The results show that lignin can
effectively modify the dynamic deformation of loess under dynamic… More >
