摘　　要：针对卵石层地质特征,以某中压燃气管道穿越工程为例,分析比较开挖换填、套管隔离、改良地层3种穿越方案。探讨燃气管道定向钻对接穿越卵石层、套管隔离、搅龙取土的技术与施工方法。According to the geological characteristics of pebble layer, taking a medium-pressure gas pipeline crossing project as an example, three crossing schemes of excavation and refilling, casing isolation and stratum improvement are analyzed and compared. The technologies and construction methods of gas pipeline directional drilling docking crossing pebble layer, casing isolation and auger soil extraction are discussed.
