| Abstract: | Based on systematic analysis on the territory of Chongqing debris flow geological development of the macro-environment,it is probable to occur large and extra large debris flow disaster in Chongqing.According to absorbent soil intensity attenuation law and indoor physical model testing,right slope mudslides and valley debris flow formation mechanism are studied.And the systematic study of the situation in Chongqing debris flow velocity formula provides the prevention a scientific basis.With the utilization of expert system approach,the situation of Chongqing debris flow developing trends is outlined,which provides a scientific basis for the comprehensive utilization of territory of land and resources. |
