一、实训目的
为了更好的将理论与实践相结合,安排了本次的教学实训,本次实训是使用全站仪进行一般极坐标点位实地放样实训。通过现场的实际操作能够使我们更熟练的掌握极坐标法一般点位放样。

四、实习过程
一、极坐标法一般点位放样
(一)、操作步骤:
1、将仪器安置于点A,在M点立照准目标定向,读为取水32?22′18″
2、顺时针转动照准部,使水平度盘读数为268?59′59″ 3、沿视线方向用钢尺量取距离D:112.310米,标定P点 (二)、附图

二、归化放样
1、用一般放样方法标定点P 1
2、方向归化,用测回法测出β=268?59′48″ 测
?β=β-β=268?59′59″-268?59′48″=+11″ 测
归化?β,顺时针微调(外测)+11″,标定P 23、距离归化,量取A P为D,?2测D=D-D=112.310-112.285=0.015米,沿视线方向量?D,标测
定P 3
4、检核?β、?D,若误差不符合要求则继续归化 四、实训总结
通过本次实习,使我们将以前学习的坐标测量知识转换为坐标的放样。将理论和实践进行结合,了解测绘和测设的区别,将地形测量的知识和工程测量的知识进行融合。使得两者相结合,即会测坐标点也会放坐标点。
用经纬仪极坐标发放样出设计坐标,并对放样出的角度和距离进行测量,比较误差和精度。让我学到了很多实实在在的东西,对以前零零碎碎学的测量知识有了综合应用的机会,工程测量测设过程有了一个良好的了解。学会了运用经纬仪的基本测设方法等在课堂上无法做到的东西以及更熟练的使用经纬仪,也对钢尺量距的知识进行了回顾。很好的巩固了理论教学知识,提高实际操作能力,同时也拓展了与同学之间的交际合作的能力。
