城市中小河道水工建(构)筑物调查测绘技术方法的探讨

Research of Hydraulic Medium-Small Rivers in City Construction Surveying and Mapping Technical Method

结合具体工程实例介绍了当前城市中小河道测量工程中常见水工建(构)筑物的类型、调查量测内容及对应精度指标、外业测绘取舍及内业成图表示方法等,特别是根据实地水工建(构)筑物的规模大小、复杂程度,探讨了对其进行调查测绘的技术方法,并结合CAD绘图系统提出了相应的解决办法。

Combined with specific examples of projects,this paper introduced hydro commonly found in the city and the river in measuring engineering structure building type,investigation and measurement field and the corresponding accuracy in dex,content choice and mapping representation method,especially explored the technology method of surveying and mapping on it on the basis of field water engineering construction structure of the building size and the complexity,and proposesd the corre sponding solution with CAD mapping system.
