The Research On Safety Design Of Underground Commercial Space In City

City is a symbol of civilization, city of civilization is the human and the naturalenvironment, social environment and psychological environment of competition andsymbiosis, transformation and adaptation of the process, it is human and technologicalprogress, economic development and social civilization.Twenty-first Century is Chinese city changes rapid development century, alongwith the global economic development and Chinese city to change accelerate theprogress, at present the city center ’s rapid growth has caused the contemporary citydesigners attach great importance to. The modern city is environmental pollution,ecological imbalance, premium prices, traffic congestion, mismanagement,neighborhood tensions, and countless other city and height of associated problemshave become increasingly prominent, which has brought people irritability andrestlessness, true it may be said" indescribable pain". But the development that thecity changes is the unstoppable, a large number of population into city to city landexpansion, which will inevitably cause ecological space and living space on the landof contradictions. While the city is the new supersedes the old. On population flow,logistics, origin to maintain, the key is the demographic factors, because of theeconomic development, population flow increases, to the city ’s development hasbrought great pressure, when the pressure exceeds a certain level, need expansion andrenovation to expand the city’s capacity. In in the course that the city changes we canclearly realize the high-rise and complex building of large-scale construction, so thatthe city ’s environmental deterioration, also destroyed the city landscape. A variety ofproblems is mixed together, restricted the city level and above to expand, so peopleaware of city underground space development and utilization in solving the problemof city where the potential formation of a city, ground and underground concept ofcoordinated development. This model can be dispersed in a city park city, green space,square and large public buildings, underground space together, consisting ofresidential, office, commercial, entertainment and leisure complex function synthesis.This paper focuses on the study of the underground construction space securityissues related to shoppers in the environment of underground space, the mentalenvironment in safety and physical environmental safety as the research foundation,from complex regional security accessibility, external and internal spa ce function space and other aspects of the analysis, to explore suitable for modern city complexunderground space development needs of the design strategy.
