英文摘要	Based on the systematic investigations of the physical properties, hydraulic properties, mechanical properties of rammed earth, material formation features and occurrence environment of six earthern ruins distributed in Xinjiang, Inner Mongolia, Ningxia, Gansu and Qinghai provinces, which were from the Han and Tang Dynasties down to the Ming and Qing Dynasties, the contributing factors and manifestation of the degradation of rammed earth were studied. And then, wind tunnel, disintegration, consistency, tensile and compressive strength experiment in laboratory on remodeling sample which had experienced dry-wet cycle after mixing different content mixing different content of Na2SO4 and NaCl were carried out, and the result showed that the coupling effect of repeated wetting-drying cycle and salinity is an important influencing factor of the degradation, verify the influence of coupling effects on physical properties, hydraulic properties and mechanical properties of rammed earth, which is represented as wind erosion resistance ability, consistency, tensile strength and compressive strength, and elucidate the internal relations between manifestation and properties of degradation of the rammed earth. Finally, the mechanism of rammed earth degradation was discussed with combining the results of qualitative analysis and experiment.
