Traditional Tibetan raw-soil-rubble stone walls are constructed from regularly-shaped stones, local raw soil, and water, where the raw-soil-water mixture serves as the bonding material with a mass ratio of approximately 3:1. This kind of wall possesses advantages of low cost, convenient construction, and favorable vertical bearing capacity, yet it suffers from large self-weight, insufficient horizontal shear resistance and poor durability. Most Tibetan-inhabited areas lie in seismic belts. Long-term repeated earthquake actions will cause cumulative damage to raw-soil-rubble walls, gradually degrade the overall structural performance, bearing capacity and seismic resistance of Tibetan dwellings, and seriously threaten structural safety. In addition, uneven masonry workmanship and the lack of rational seismic design will lead to severe cracks or even collapse of buildings during earthquakes. Therefore, it is of great significance to explore the seismic failure mechanism and evolution law of raw-soil-rubble walls, propose effective seismic reinforcement measures and optimize wall structural design for the protection of Tibetan architectural heritage.

t with stones, timber, and yellow mud. Although easy to construct, they generally have drawbacks, including inconsistent construction quality and low strength of bonding materials. In the long-term service period, common damages such as wall cracks, surface spalling and local collapse frequently occur. Successive seismic events further degrade material properties, structural bearing capacity, and stability. Without targeted seismic design, traditional Tibetan dwellings are highly vulnerable to earthquake damage, which poses a grave risk to residents’life-and-property safety. Hence, research on the dynamic response law and seismic performance of traditional Tibetan dwellings under earthquakes is an urgent fundamental engineering problem to be solved.
