摘　　要：在油气管道穿越工程中,特殊地质条件下大口径顶管施工作业容易发生管路抱死现象。为解决这一问题,采用了对接顶管施工技术。结合西气东输二线施工案例,对施工过程中的测量及纠偏技术进行了探索和研究,为今后在无水砂卵石等特殊地层条件下的顶管施工提供了有效的方法和依据。In oil and gas pipeline crossing construction under particular geological conditions, large diameter pipeline stuck phenomena often happen in pipe pushing operation. In order to solve such problems, the technique of pipes pushed from both sides till butt jointed is adopted. Associated with the cases in Second West to East Gas Pipeline Project, the research on measurement and deviation rectifying during pipe pushing is conducted. The research results also offer an effective base for other pipe pushing construction under particular geological conditions such as dry pebble sand stratum.
