摘要
山区高速公路综合造价分析中,由于地形复杂性和数据获取的局限性,难以精确测量位置、长度、坡度、坡向等关键参数,导致综合造价评估的准确性和效率受到限制。这种局限性使得无法高效整合空间数据存储,单点定位模型、空间分析及统计分析方法,从而难以实现综合造价的精准评估。为了解决这一问题,提出基于地理信息系统(Geographic Information System,GIS)与北斗定位技术集成的综合造价分析方法。利用北斗指挥机、Java监听扫描程序、GIS服务和数据访问接口构建技术框架,结合北斗终端和北斗基站对山区高速公路的位置和长度进行精确测量,通过通信协议和GIS业务逻辑将测量数据传输至GIS空间数据库存储。在此基础上,利用单点定位数学模型获取测量结果,通过GIS空间分析提取坡度、坡向数据,最后结合统计分析方法,依据位置、长度、坡度等关键参数,实现对山区高速公路综合造价的精准评估。实验结果表明:该方法能够有效集成GIS与北斗定位技术,能利用北斗定位技术获得山区高速公路标定点定位结果和长度数据,运用GIS获得山区高速公路坡度和不同项目综合造价分析结果,应用性较强。
In the comprehensive cost analysis of mountainous highways,due to the complexity of terrain and limitations in data acquisition,it is difficult to accurately measure key parameters such as location,length,slope,and aspect,which limits the accuracy and efficiency of comprehensive cost assessment.This limitation makes it difficult to efficiently integrate spatial data storage,single-point positioning models,spatial analysis,and statistical analysis methods,preventing accurate evaluation of comprehensive costs.To address this issue,a comprehensive cost analysis method based on the integration of GIS and Beidou positioning technology was proposed.Using Beidou command machine,Java monitoring and scanning program,GIS service and data access interface,a technical framework was constructed.Beidou terminal and Beidou base station were combined to accurately measure the location and length of mountainous highways,and the measurement data was transmitted to GIS spatial database storage through communication protocol and GIS business logic.On this basis,a single-point positioning mathematical model was used to obtain measurement results.Slope and aspect data were extracted through GIS spatial analysis.Finally,statistical analysis methods were combined to accurately evaluate the comprehensive cost of mountainous highways based on key parameters such as location,length,and slope.The experiment showed that this method can effectively integrate GIS and Beidou positioning technology,and use Beidou positioning technology to obtain the positioning results and length data of mountainous highways.It can also use GIS to obtain the slope and comprehensive cost analysis results of mountainous highways and different projects,showing strong applicability.
