| 摘 要： | 随着非开挖水平定向钻进（HDD）技术的发展和推广应用，清晰而准确的反映施工轨迹与设计轨迹的偏差成为评判工程质量的一个重要指标。本文应用极等间距网与笛卡尔坐标系结合构成的复合坐标系，将非开挖施工轨迹与设计轨迹的偏差绘制在坐标系中，直观的反映了施工后实际轨迹与设计轨迹的偏差程度，对轨迹的验收具有非常直观可靠的意义。

| Abstract: | With the development and promotion application of the trenchless horizontal directional drilling (HDD) technology, reflecting the deviation between the construction path and the design path became an important indicator of the quality. The paper introduced that the deviation between the construction path and the design path were drawn in the coordinate system, using the composite coordinates combining the Polar iso-distance net and Cartesian coordinate system. This method reflected the deviation between the construction path and the design path intuitively, and it had very intuitive and reliable significance for the acceptance. |
