  • The accumulation body group is an aggregate of accumulations. It can be seen everywhere along the upper reaches of Jinsha river. It is a big problem to limit the progress of hydropower development at this area. This paper examines the problem using a project of a hydropower station at upper reaches of Jinsha river. This place is strongly affected by geological structure and climate. The ancient accumulation body group lies on the right bank of the upper reaches of Jinsha river. Its size is almost three million tons and its geological structure and origin can not be certain. It is located just only about one kilometer distance to the hydropower station. So it will be a big problem of the hydropower project. Three methods are applied to analyze the problem in this paper. They are topographic feature analysis, rock structure theory, and analogy analysis. Finally, four results are achieved.(1)on the basis of topographic feature, the accumulation group can be divided into four domains.(2)Comprehensive topographic and geological structure feature analysis results are achieved that river blocking had happened at this area.(3)the product period of domain Ⅰ is earlier than the other domains. However, the river blocking was not happened during the period of domain I production. The production of domain Ⅰ just made the river diversion.(4)the structure of domain Ⅱ have a separation grade feature from up to down. This is a typical character belong to debris flow. So the conclusion is that the domain Ⅱ was come from anti-shore. The true river blocking was happened after the domain Ⅱ production.
