基于GIS的青岛市工程场地评价可视化研究
|
摘要
本文主要完成了以下几大模块:①以规范模型为基础,首先智能判别单个钻孔的场地所属类别和砂土液化情况,然后采用插值方法插值成面状场地类别分区和砂土液化分区图,并动态加以展示;②根据先前输入的钻孔资料信息自动生成基岩顶部等值线图;③根据资料得到青岛市断层分布,然后依据规范规定,应用缓冲技术给出建筑避让距离;④展示所应用的判别规范,允许用户添加和更改。根据以上几点处理,基本达到了工程场地评价的可视化,为相关部门提供了方便工具和直观资料。
This paper consists of following parts: First, differentiating single bore field sorts and liquefaction status intelligently, using interpolation method to form zonation map of planar field sorts and sand liquefaction, and then displaying analytical results dynamically. Second, automatically generating contour map of the depth of bedrock top by using bore data inputted in advance. Third, obtaining Qingdao fault distribution from data and calculating building lien distance by using buffering technology. Fourth, displaying the code which author used, allowing users to add or edit. Based on above points, the visualization of engineering field evaluation is basically achieved which provides convenient tools and intuitional materials for relevant departments.
