Abstract
Based on the geological environment about Fuling district in Chongqing city, eight evaluating indicators on road flooding subsequently environment along the highway: geological disasters developmental condition, rainstorm intensity, flood frequency, landform condition, litho-logical condition, average annual rainfall, vegetation coverage and geological structure, have been chosen. Adopting expert system to double evaluation and using the analysis hierarchy process to confirm the weight of index, accordingly, the mathematical model of evaluation on subsequently environment is put forward. On the support of GIS, grid subsequently environmental index and township administrative division subsequently environmental index, subsequently environment is divided into 4 degrees. They are dangerous zone, high susceptible zone, middle susceptible zone and low susceptible zone of the floods subsequently environment around highway. The results of the study indicate that in the total area, dangerous zone, high susceptible zone, middle susceptible zone and low susceptible zone of road flooding are 11.89%, 41.65%, 32.20% and 14.26% respectively. The results provide some significant scientific evidence for the further risk evaluation of road flooding.
