China has a history of ground crack disaster for a long time,the activities of ground crack threaten the normal use of houses and the safety of people’s lives and property,the need of urban development has put forward new requirements for the use of ground crack site.Construction of urban wind duct is to improve the urban wind environment,weaken the urban heat island effect,enhance urban ventilation environment and improve residents living comfort important measures,urban scale,wind size,wind duct construction scale and wind duct boundary area environment requirements is the main factor affecting urban air duct ventilation effect,is also the urban wind duct construction need to consider the important conditions,in addition to the construction of urban wind duct also need to fully combine the city local since However,according to the different areas of the regional wind duct construction.In this paper,through the research of domestic and foreign theoretical experience,online data collection,computer simulation,the prevention and control and the influence of the urban wind landscape,in the micro scale,respectively,building,plant,micro landscape and water different landscape elements,designed to enhance the guidance and penetration of natural wind in the urban environment.In the urban scale through the ground crack prevention and the city Wind duct planning is combined,and CFD numerical simulation technology is used to simulate the urban model of building avoidance on the ground cracks,and to guide the wind duct planning and design of the urban ground cracks with simulated data.Xi’an residential area,for example,through the Wind PerfectXD software of residential building wind environment and green wind environment simulation,and on the basis of crack control method and wind duct construction requirements,according to the site crack direction and wind environment simulation of residential buildings and green space layout optimization design,discusses the micro scale crack wind duct landscape design points,summarizes the application of computer simulation technology to the city The landscape design of the regional wind environment analysis. |
