“…Many scholars have conducted extensive research on earthen heritage site soil. [4] Research findings, under the action of rainfall and snowmelt, the migration of water and salt in the earthen heritage site is intensified, resulting in surface crusting, cracks, and the formation of salt alkali zones at the bottom of the earthen heritage site. [5] Study was conducted on the use of polyvinyl alcohol (PVA) treated soil as a weathering resistant material for earthen heritage site.…”

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.

Frost events can cause the deterioration of a wide range of heritage materials, including stone, brick and earth. In a warming world, the frequency and location of frost events is likely to change, affecting the conservation strategies required at heritage sites. We use a multi-model ensemble approach to investigate three types of frost events in East Asia: freeze–thaw cycles; deep frost days and wet frosts. The study uses nine CMIP6 models for the period 1850 to 2100, with future projections run under the SPS585 scenario. Additional analysis is undertaken for five specific 2° ✕ 2° areas located across East Asia. The three frost event parameters are spatially and temporally distinct. A decrease in all three frost parameters is found in Japan, South Korea and East China, with some areas projected to have no frost events by the end of the twenty-first century. However, Northwest China is distinctive as wet frosts are projected to increase over the twenty-first century, while on the Tibetan plateau of Southwest China, freeze–thaw cycles are projected to increase. This suggests that except in some localised regions, heritage managers can focus on risks other than frost weathering in developing plans to address climate change. Graphical Abstract
