Abstract: Evaluation of engineering geological environment and construction of urban layout compose a multi-factors and multi-levels process. How to choose and use condition of engineering geological environment, protect and control the possible engineering geological problem, reduce the occurrence of geological hazard is very important in urban layout. In this paper, we investigate the engineering geological environment comprehensive evaluation with intuitionistic fuzzy information. Motivated by the ideal of dependent aggregation, we shall propose the dependent intuitionistic fuzzy Hamacher weighted average(DIFHWA) operator, in which the associated weights only depend on the aggregated intuitionistic fuzzy arguments and can relieve the influence of unfair arguments on the aggregated results by assigning low weights to those “false” and “biased” ones and then apply this operator to develop an approach for engineering geological environment comprehensive evaluation with intuitionistic fuzzy numbers. Finally, an illustrative example for engineering geological environment comprehensive evaluation is given to verify the developed approach.
