Geological Suitability Evaluation for Urban Underground Transportation Space Utilisation in Soft Soil Area

Geological suitability evaluation of urban traffic underground space utilisation is an important basic work in planning, especially for soft soil areas. In this study, firstly, on the basis analyzing influencing factors transportation areas, and considering such as topography, geotechnical properties, hydrogeology, existing constructions, index system was constructed. The weights are comprehensively determined according to expert scores literature research. Then, quantified by AHP (analytic hierarchy process) method study area calculated multi-objective linear weighting established model. Finally, taking Wenyi Road Hangzhou example, using model carry out application research geological utilisation. results can provide technical reference
