Abstract

In order to address the safety issues caused by the tilting of the earthen heritage site, the unsaturated soil triaxial shearing and permeability instrument was used to conduct humidifying tests under deviator stress conditions. Studied the humidifying deformation characteristics of artificially prepared earthen heritage site by using glutinous rice slurry as a repair material. When the deviator stress is small, the glutinous rice slurry exerts a bonding effect, and the humidifying deformation of artificially prepared earthen heritage site is smaller than plain soil; the increase in deviator stress disrupts the bonding effect between glutinous rice slurry and soil particles, the lubricity of glutinous rice slurry leads to greater humidifying deformation of artificially prepared earthen heritage site than plain soil. When the net confining pressure is high, the sample is compressed and compacted, and the cohesiveness of glutinous rice slurry plays a role. The humidifying deformation of artificially prepared earthen heritage site is smaller than plain soil, the improvement effect of glutinous rice slurry is the best at this time.
