Abstract:
In order to fully approach its structural property and master the deformation regularity of whole stressing for “subtraction law” shaping structure, authors used a nonlinear finite element analysis program ABAQUS to establish a whole model for underground cave dwelling and conducted a step-by-step analysis according to a practical digging and shaping process and obtained its initial stress field and discussed its development and change of stress, displacement and plastic ranges in each step of digging and downloading. The research result of the paper has supplied a scientific basis for exploring the structural secret in which underground cave dwellings have survived for a hundred or even several hundred years without collapse and studying the structural safety and reliability of underground cave dwellings in service.
