Abstract:Urban underground space is a valuable resource, it plays an important role in solving the problem of traffic congestion, optimizing the allocation of urban functions, improving environmental quality and improving infrastructure. Rational development and utilization of underground space is an important way to achieve the goal of carbon peak and carbon neutral, promote intensive land use and complete urban green, low-carbon and sustainable development. By analyzing the main characteristics of underground space utilization, this paper puts forward relevant measures for underground space development and urban energy conservation and carbon reduction, and applied in specific engineering cases, so as to reduce energy consumption and carbon emission, It provides a certain reference for the early realization of carbon peak and carbon neutral.
