BIM技术在城市园林景观竖向分析中的应用研究——以南京市青龙绿带二期工程为例

Application Research of BIM Technology in Vertical Analysis of Urban Landscape Take the Nanjing Qinglong Greenbelt Phase Ⅱ Project as an Example

基于风景园林行业的信息化要求,借鉴建筑工程领域的BIM技术,将其应用到城市园林景观竖向分析中。以南京市青龙绿带二期工程为例,基于BIM技术软件Civil 3D创建原始场地三维数字曲面模型,对项目高程、坡度、坡向、流域、径流进行量化分析,为竖向设计提供依据。同时景观工程全寿命各阶段都可以对场地数据进行提取与分析。

Based on the information requirements of the landscape architecture industry,BIM technology in the field of construction engineering is applied to the vertical analysis of urban landscape.Taking Nanjing Qinglong Greenbelt PhaseⅡProject as an example,this paper creates a 3D digital surface model based on BIM technology software Civil 3D,and carries out quantitative analysis on project elevation,slope gradient,slope direction,and confluent runoff,so as to provide a basis for the vertical design.At the same time,the site data can be extracted and analyzed at all stages of the whole life of landscape engineering.
