ABSTRACT

In this paper, by using the basic functions of AutoCAD, the oil pipeline intensive areas stimulate the offset design point, combined with practical application, making construction task graph which can better solve problems of excitation point offset at the construction site; the following introduces the realization methods and its use effect.

1. 引言

2. 准备工作

1) 尽量搜集甲方GIS部门提供的油井管线信息和以往该地区施工的信息。

2) 准备多个Garmin Etrex导航仪，为实地采集信息做准备。

3) 利用现有软件Google Earth 6.0.0.1735，GPS Trackmarker13.7和Autodesk Map 2004分别进行探区地表信息的识别、导航仪数据的处理以及进行物理点偏移设计等工作。

3. 以某项目为例

1) 项目概况

Figure 4. Drawing all structure lines in working area

Figure 5. Snap the intersection of structure line and safety distance line

Figure 6. Label the minimum safe distance

Figure 7. Label all the source point which need offset

Figure 8. Remove the structure line layer

Figure 9. Final Construction Task Graph with offset design

6) 将图件打印出来，分发到测量施工小组，作为实地激发点偏移的参考，进行野外放样，可根据情况再进行调整。如激发点50471550需要向测线的左测方向垂直偏移165.5049米(可取整为166米)。这样既保证了激发点与障碍物之间的安全距离，又满足了QC要求。

4. 应用效果

5. 结束语
