摘　　要：水平定向钻是一种非开挖的修复或更换各种地下管道和电缆的施工工艺。与传统开挖施工穿越技术相比,水平定向钻技术在提高施工效率,缩短工期、降低造价和环境保护都有许多优越性。本文主要总结了使用水平定向钻技术穿越黄河的管道,并对此提出对黄河中下游的管段穿越的一些意见。在此基础上,开发了水平定向钻的一般穿越曲线设计的程序。Horizontal directional drilling is a non-excavation construction process for repairing or replacing various underground pipes and cables.Compared with traditional excavation and crossing technology,horizontal directional drilling technology has many advantages in improving construction efficiency,shortening construction period,reducing cost and environmental protection. This paper mainly summarizes the pipelines that use horizontal directional drilling technology to cross the Yellow River,and puts forward some opinions on the pipe crossing of the middle and lower reaches of the Yellow River. On this basis,a program for the general crossing curve design of horizontal directional drilling was developed.
