地铁隧道结构断面测量方法探讨及编程实现

地铁隧道的结构断面测量是铺轨建设期间的一项重要工作,常规的测量方法内外业工作量较大,内业处理较为繁琐,数据计算效率较为低下。为了尽可能提高测量工作效率,减少仪器成本及人工成本,探讨了在地铁隧道内的控制点上架设全站仪,采用三维坐标测量的方法测得每个结构断面的特征点坐标,进而计算相应的断面尺寸偏差,并用C#编程语言编制了计算软件,使数据处理更为方便。工程实践表明,相比传统测量方法,该方法可以减少一定的外业工作量,同时内业数据处理相对简单便捷,效率高,可为类似工程提供参考。     

BIM技术在桥梁设计应用研究

BIM technology is widely applied in the engineering field, and is the important orientation of the future development. BIM technology is briefly analyzed. The basic principle of BIM model data structure is put forward. Taking the infrastructures of Shangri-La and the surrounding road network comprehensive regulating projects as the examples, the processes of Revit component modeling and project modeling are explained. The key information is extracted from the component and project models. Through the secondary development means to output the construction drawings, the method and principle of Revit to output construction drawings are summarized, which provides the new thinking for the application of BIM technology in bridge design.
