天然气管道水平定向钻穿越公路的相关应力计算

Stress calculation on horizontal directional drilling for natural gas pipeline crossing road

通过工程实例进行无套管钢管定向钻穿越高速公路的应力计算和校核,验证了无套管钢管定向钻穿越高速公路的可行性。

This paper describes the case study of stress calculation and checking on the directional drilling crossing the expresswaywith non-casing steel pipe. The result proves the feasibility of the technology in crossing the highway.
