Development and Application of Karst Foundation Evaluation System Based on GIS

Analysis and evaluation of the stability of road and bridge foundations in karst areas is currently one of the major technical problems in highway construction at home and abroad. Secondly, on the basis of the grey evaluation model of water quality, the principle of maximum entropy in information theory is introduced to establish a grey evaluation model of karst groundwater environment based on entropy that can satisfy the evaluation of karst groundwater environment, so as to realize the mathematical evaluation of karst groundwater environment and karst groundwater quality. In the pre-planning of the highway, GIS can facilitate the planning, site selection, analysis and decision-making of the best route of the road network. At the same time, it can also analyze the environment along the highway.
