水平定向钻法穿越公路工程钢套管强度验算分析

Analysis on Checking Calculation of Strength of Steel Sleeve crossing the Highway Engineering with Horizontal Directional Drilling Method

近年来,采用水平定向钻法施工穿越公路的案例逐渐增多。文章以某电力线改造工程为例,对钢质套管内力的验算方法进行分析,认为石油管道工程验算方法是基于测量各条件下管线实际性能的经验总结得出,其结果更符合实际情况,建议可采用此方法进行钢管结构强度验算。

In recent years,there has been an increasing number of cases of highway crossing construction with horizontal directional drilling method.Taking a power line reconstruction project as an example,the checking calculation method for the internal force of the steel sleeve is analyzed.It shows that the checking calculation method for the petroleum pipeline engineering is obtained based on the summary of experience of measuring the actual performance of the pipeline under various conditions,and the result is more in line with the actual situation.It is suggested that this method can be used to perform the checking calculation on the strength of the steel pipe structure.
