复杂地质条件下长输油气管道施工期保护措施探讨

Discussion on Protection Measures of Long-distance Oil and Gas Pipeline Construction Period under Complex Geological Conditions

摘要

长输油气管道工程常穿过滑坡、岩溶、冻土等复杂地质区域，施工期地质灾害容易引发管道变形、破裂之类的安全隐患，直接危及工程建设质量与后期运营稳定性。本文结合复杂地质条件类型及特点，施工期管道面临多种主要风险，像地质灾害引发机械性损伤、地基不均匀沉降致使结构失效、施工工艺不当造成人为破坏等，需进行分析，从地质预处理、施工工艺优化、监测预警体系构建这些方面给出针对性的保护措施。凭借工程实例验证措施有效性，该案例工程实施上述保护措施后，施工前期边坡位移小幅上升，后期变得稳定，最大累计偏移数值18.5mm，给同类工程供应技术参照。

Abstract

Long-distance oil and gas pipeline projects frequently traverse complex geological zones including landslides, karst formations, and permafrost. During construction, geological hazards may trigger pipeline deformation or fractures, posing direct risks to both engineering quality and operational stability. This study identifies multiple critical risks under complex geological conditions, such as mechanical damage from geological disasters, structural failure due to uneven foundation settlement, and human-induced damage from improper construction techniques. Targeted protective measures are proposed through geological pre-treatment, optimized construction methods, and early warning monitoring systems. Case validation demonstrates that after implementing these measures, the slope displacement during the initial construction phase showed a slight increase but stabilized later, with a maximum cumulative displacement of 18.5mm. This provides valuable technical references for similar projects.
