Analysis of the infrastructure system and core factors for environment-friendly urban regeneration

摘要

These days, cities have dramatically expanded due to over-population, the concentration and extension of urban functions. As a result, multiple urban renewal projects have been planned and executed to strengthen the efficiency of urban functions and improve living environment. Because of the constraints of urban ground space, there have been limitations in the improvement of urban functions through the horizontal expansion of urban spaces. Therefore, it is necessary to set underground express ring roads which can be highly applicable to urban development and improvement as target infrastructure, examine the location conditions and ripple effects of the development, collect necessary information for conceptual design and estimate weighted values by core element technology for construction of the infrastructure. When underground transport infrastructure constructed in the downtown, there are many technical problems to be solved such as interaction between underground facilities and the existing facilities on the ground, tunnel stability, ventilation and environmental problems. Hence, this paper investigated the matters and technical problems that should be considered during the construction of underground space and analyzed the technologies that are necessary in developing urban spaces based on patent trend analysis in construction of underground spaces.
