Evaluation of bearing capacity and stability of caves on the cliff of traditional dwellings in northern Shaanxi
In order to study the bearing capacity and stability of cave on the cliff of traditional dwellings in northern Shaanxi Province,through on-site detection and investigation of the damage of cave on the cliff and the impact of collapse area on the overall structure,finite element software ABAQUS was used to analyze the bearing capacity and stability of sin-gle cave cave and the whole cave-slope.The research results show that:The serious damage of cave on the cliff is mainly distributed in the cave leg and arch roof.The main diseases are cave leg cracking and external flash,arch cracking,local loosening and even collapse.The foundation in the collapse area is inclined and cracked due to the stress release.The ca-ve-dwelling monomer is less deformed and stressed under external load and less affected by earthquake.When the cave-slope model is unstable,the strength reduction coefficient is 1.15.On the surface,the slope is currently in a stable state,and there is a risk of instability in a large amount of precipitation.
