| 摘 要： | 对非开挖工程中水平定向钻进轨迹最优化设计进行了深入研究。应用最优化理论的动态规划思想,以钻进台时为优化指标,根据障碍物位置、大小和钻孔参数,建立了轨迹设计的最优化模型;并推导出绕过两个障碍物的局部轨迹最优化函数,通过坐标变换,简化了兰维空间轨迹设计问题;开发了相应的软件实现模型的求解。

| Abstract: | This paper discussed the horizontal directional drilling trace optimization design in no-dig engineering. Applying the dynamic program thought of the optimization theory, taking the penetration speed as optimization target, and based on the position and size of obstacles, and bore hole parameters, the paper presents a optimization modal of trace design, derives universal local trace optimization function between two obstacles needed to bypass, by revolving transform the coordination, simplifies the design in 3-dimension space; and develops a special software to resolve the modal. |
