Drilling track is key factor which decide trenchless success or failure, but controlling drilling track stay around rectifyed phase at the present. guided the theory of force is the key affectting the drilling track, the paper discuss primary factors on contralling drilling track, and advance the formulary ahout reckoning deviation force and azimuth force, expect to achieve the aim that drilling track were controled real time and be anticipated, and have the initiative on drilling track contaolling
巖層鉆進軌跡是決定非開挖成敗的關鍵因素，目前對鉆孔軌跡的控制僅僅停留在被打糾偏層面上，本文在力是影響鉆進軌跡本質因素理論指導下，對影響巖層鉆進軌跡控制的因素進行了理論探討，並針對造斜力和變方位力提出了計算模式，希望最終能實現鉆孔軌跡的實時監控與調整，變被打糾偏為主動鉆進。 -
