МОРФОЛОГІЧНА МОДЕЛЬ РОЗВИТКУ ПІДЗЕМНОЇ ІНФРАСТРУКТУРИ ВЕЛИКИХ МІСТ ДЛЯ МІНІМІЗАЦІЇ ЕКОЛОГІЧНИХ І ТЕХНОГЕННИХ РИЗИКІВ УРБАНІСТИЧНОГО ПРОСТОРУ

Purpose. Development of a morphological model for development of underground infrastructure of large cities (including lengthy structures for transport purposes) to minimize ecologic and technogenic risks of urban space. Problem. Using the modified morphological analysis methodology, develop a system of morphological tables that take into account both the influence of geological environment factors and the structural-functional characteristics of territories on the risks of ecological and technogenic threats.Research result. The morphological tables of geological engineering factors for a construction site, decision elements regarding a tunnel track, structural-functional influence parameters, as well as cross-consistency matrices for these parameters were constructed. An experiment with artificial increase of probability for the alternative «Quicksand/flooding present» allowed to evaluate the model reaction to this influential factor.Scientific novelty. For the first time the goal function of morphological model for developing underground infrastructure of large cities is the minimization of ecological and technogenic risks of urban space. A technique is proposed for accounting the variability of parameter alternatives along the tunnel track using expert estimations. The impact of factor “Quicksand/flooding present” on the favorability of a site (tunnel track) was determined. Conclusions and practical value. The developed morphological model opens up the possibilities for system analysis of transport infrastructure of a metropolis, and assessing the propriety of partial transfer of transport functions to car tunnels at planned sites.
