The earth' s surface deformation characters of Wenchuan earthquake are rich and colorful. After 40 days from the earthquake occurrence, the authors put through a special subject investigation and analysis of the earth' s surface deformation phenomena from the north the south, and anatomized emphatically the 8 fault crop-out such as, Beichuan, Leigu,'Hanwang, Yinghua, Bailu, Xiaoyudong, Hongkou and Yingxiu. The results show an uniform deformation and dislocation pattern for different sides and grades phenomena, but the situation is much more complex than theoretic models and rule. It shows that upheaval is formed along Wenchuan seismic fault plane jostling, lengthways and cross cracks are formed, the compressed foreland crashes and collapses and forms thrust accumulation wedge bodies, compression or tension occurs in many directions in which show complexity of the deformation combination, these enrich the stress action theory in different degree.
