Waterfront Commercial Street Interface Design Coordinated With Wind Environment

The development of urbanization has,on the one hand,improved the quality of life and quality of life of residents,and on the other hand,it has also exerted tremendous pressure on the environment.Urban climate characteristics are an important factor influencing urban life,and urban waterfront is the main area where residents gather.The waterfront street interface serves as the boundary of the external space environment of the waterfront and is one of the waterfront visual center Urban street waterfront districts are excessively pursuing commercial interests in the street design,neglecting the increasingly prominent internal and external environmental problems in the streets.From the perspective of professionalism,planning practitioners should take into account the environmental quality of the external space of the city on the basis of the planning of the physical space and create high-quality urban and external space for life to be solved.This paper mainly evaluates and explores the wind environment monolithic and superimposed simulations of the traditional design elements of the waterfront street interface,with a view to providing a design approach and technology for the design of the street interface of the waterfront area in collaboration with the quantitative design of the wind environment design.This study first analyzes and compares the methods and strategies of traditional urban and rural planning and design,and methods and strategies of urban wind environment design,and discovers the links between the two,and based on the wind environment design theory method and design flow,Establish a methodological system that adapts to the wind environment simulation of the waterfront of small and medium cities.The methods,policies,and measures for existing wind environment simulation evaluation methods were summarized and analyzed.The average wind speed,comfort wind ratio,and wind dispersion(wind Uniformity)The three indicators were comprehensively simulated and evaluated to construct an evaluation strategy for urban wind environment.From the design elements of street interface design(such as rigid index volume ratio and elastic index building modeling,etc.)and superimposed design elements,the relationship between street interface design and ventilation design in the waterfront area is explored.Through the simulation and quantification of street enclosure interface index enclosure method,aspect ratio,gradation,architectural modeling,gluing rate,continuity,average height(volume ratio)and wind environment design index(average wind speed,dispersion,etc.)The ventilation rules and characteristics of each impact factor at pedestrian height(1.5m)were obtained.Using the relationship between the street composition of 16 different ways and the wind environment design indicators(average wind speed,dispersion,etc.),analyze the ventilation rules and characteristics of different streets under the factor superposition,and summarize and summarize the influencing factors of the street interface to the wind environment.,Combined with the sample case Wanzhou District Longhua City Commercial Street for finishing use,and analysis and evaluation of the ventilation effect and ventilation quality at the pedestrian height(1.5m)of Longhua Street in Wanzhou District in summer,from the overall design,planning and construction of urban streets The level summarizes the redesign method of the wind environment in the coastal area of the city.The research thinks: First,through the actual measurement,under the current technical conditions,selecting CFD phoencs software as a wind environment simulation method is feasible in the planning practice,and the operation result is relatively reliable.2.According to the case study of Longhua City Street in Wanzhou District,the idea and method for the study of the waterfront street interface design that is coordinated with the wind environment can better guide the planning and design of the street interface and can satisfy the reasonable planning of the physical space of the street.Based on the design,the quality of the internal and external environment(ventilation)of the street will be improved,and the shape of the commercial street will be relatively well-coordinated with the comfort of the wind environment.
