'一、课程设计的目的、性质为了培养应用型人才,根据我校测绘专业的实际情况,此次课程设计的目的主要有以下几点:1、培养学生对测量数据进行工程实际应用及综合曲线中曲线内部加密桩号坐标的计算和分析能力。2、加强理论与实践相结合进一步深入理解理论,提高对道路勘测设计、工程测量学等教材的熟悉与应用能力。3、提高学生应用计算机及编程来处理测量数据的能力,以此来提高精度要求。4、锻炼和提高学生分析问题、解决问题的实际能力。本次课程设计的性质为集中教学,课程设计的时间为2011年1月4日到1月14日,各同学应到指定的教室作业。自己查找相关的参考资料、自己推证必要的计算公式、自己计算数据、自己编写课程设计报告。二、课程设计的任务与要求(一)、任务本次设计的任务较为繁重,计算工作较大,设计的相关内容较多,每位学生的主要任务有:1、高等级道路中线整桩点里程与坐标计算。2、在地形图上根据等高线及设计高程计算场地平整的填挖分界线及土方量的计算。(二)要求
每人必须在规定的时间内完成课程设计,具体要求如下:1、能够应用道路勘测设计的基础理论,尤其是道路中缓和曲线的数据处理,计算出平面的坐标与大地坐标转换。利用CAS漱件成图,完成道路设计略图。2、能够应用工程测量学中基础理论对地形图处理相应的土方量计算,然后用CAS函件成图。3、理解各种计算原理、模型的正确性,方法可行,提倡用EXCEL或VB编程等工具计算,但禁用网络上相关软件进行数据处理,以防精度不够及失控。(三)课程设计的组织安排与管理每班安排一名指导老师,我们测绘0742班由高平和老师负责指导。由于在设计中每位学生需要用计算机处理大量的数据而且需要查阅大量相关测量方面的书籍与文献等,故在时间上实行动态管理。其它时间由班长、班委会成员负责指导老师以外的纪律管理工作。三、课程设计的基本内容(一)、高等级道路整桩点里程与坐标计算1、已知数据如表1路段IP1K1+576.0764774634.521495567.594IP2K3+527.1464775585.76-"493382.504IP3K4+876.0534775557014492013287第一缓和曲线起点ZH第一缓和曲线终点或圆曲线起点HY曲线中点QZ第二缓和曲线起点或圆曲线终点YH第二缓和曲线”占一S八、、HZK2+794.457K2+944.457K3+516.840K4+089.223K4+239.223转角值转向左角度(°"〃)244341.53半径R缓和曲线长度切线长度曲线长度L夕卜距E
