During the 1∶50000 scaled regional geological survey, the theory of non-Smith stratum in orogenic belt is adopted, with structure analysis and ductile deformation zone research method, to systematically study the structural deformation of the strata.

Through inversion of aseismic negative dislocation model and analysis of time-space evolution of deformation and strain fields for horizontal velocity data measured by GPS in 1991～1999 and 1999～2001 in Sichuan-Yunnan area,combining with geological tectonic deformation features of blocks and their boundaries and their relationship to development of strong earthquakes are studied.

Based on the experimental results from a mine and the mechanical parameter measurement of the cemented filling body, the stress distribution and deformation behavior of the cemented filling body are investigated by use of the numerical simulation.

The result shows that the silt hollow RC shear wall presents ductile bending-shear failure model,its ductility and deformation behavior are advanced because of its failure model.
