摘　　要：随着我国天然气运输业的蓬勃发展,油气储运规模不断扩大,管道的直径亦是越来越大。由于油气管道在施工过程中涉及到许多关键技术,特别是在定向钻穿越技术等高难度的施工技术,在施工前期的勘察阶段应对定向钻穿越在施工过程中可能面临的问题进行提前考虑,以保证施工的进度与质量。本文通过对管道定向钻穿越的工程地质条件的总结,探讨了定向钻穿越过程中的施工问题,提出了合理的施工措施。With the vigorous development of China's natural gas transportation industry, the role of natural gas pipeline crossing in natural gas transportation is becoming more and more important. When Gaoshiti-Moxi gas pipeline project crosses the Yangtze River, in order to find out the engineering geological conditions of the crossing section accurately, so as to select the best pipeline path, so as to formulate the corresponding construction scheme in advance. By analyzing the engineering geological conditions of the project area, this paper analyzes the influence of river erosion, site bank slope, surrounding rock stability and tunnel water gushing on the pipeline, and puts forward reasonable construction measures.
