| 摘 要： | 偏心钻头在钻进的过程中轨迹呈曲线，而影响曲线曲率半径的原因是多方面的。在对冲击矛及土体做了若干假设的基础上建立起了冲击矛受力的力学模型，从力学的角度对可控冲击矛的钻进轨迹进行了深入的理论分析及研究，从本质上找出了可控冲击矛轨迹变化的根本原因。

| Abstract: | The trace of beviation bit is curve during drilling.The reason that affects the radius of the curve is various.We made the mechanical model on the basis of some hypothesis of the controllable impact mole The analysis and research work of mole trace have been done.So we have found out the direct reason that affect the mole trace. |
