Abstract

Abstract

Since the "Twelfth Five-Year Plan", the contradiction between the rapid expansion of space demand and the limited space resources in megacities has become increasingly prominent.The development and utilization of underground space has entered a rapid development stage.Under this situation, understanding the carrying capacity of underground space is of great significance for scientific planning and rational utilization of underground space.From two perspectives, carrying background (reflecting the endowments of underground space resources and the pros and cons of the environmental capacity) and carrying actuality (reflecting the matching degree of the capacity of the underground space resource and the economic and social development), the evaluation index system was built, and evaluation of underground space carrying capacity was studied to provide technical support for the development and utilization of underground space in megacities.The central city of Shanghai with limited space resources was selected as a case to evaluate the underground space carrying capacity, and the bearing capacity of underground space resources was displayed in three dimensions with the help of 3D modeling technology.The results show that the carrying capacity of the underground space resources in the central city of Shanghai is generally good, and the underground space can be further developed rationally to improve the urban space utilization and alleviate the pressure of limited space resources.
