摘要
以清水海供水及水源环境管理工程特大型施工控制网为实例,分析了控制网优化设计的具体思路和流程,剖析了解析法或模拟法优化设计的优缺点,提出了采用Google Earth软件配合常规模拟法优化设计的新思路,详细介绍了Google Earth在控制网优化设计中应用的具体方法,充分利用Google Earth软件丰富的地理信息资料和直观三维模型进行选点布网和确定通视情况,阐述了采用Google Earth软件配合常规模拟法优化设计的优点。
Taking the control network of Qingshuihai project,a super huge construction of water conduct as an example,we analyzed the concrete idea and flow of optimization designs of the control network and dissected the advantages and defects of them using analytical and analogous methods respectively in this paper.Combined with the concrete project,we proposed a new idea for optimization design of the control network,which adopts the software Google Earth to assort the conventional analogous method,and introduced the feasibility and the concrete method of the application of Google Earth to the optimization design of the control network in detail,and fully utilized the rich geographic information and the intuitive 3D model from Google Earth to selecting the control points and to determine the intervisibility,and expounded the advantages of adopting Google Earth to assort the conventional analogous method.
