摘要：

为了合理评价山区受崩塌落石威胁的油气管线工程安全性，分析管道在落石冲击作用下的动力响应特性. 通过开展埋地油气管道的落石冲击足尺模型试验，结合试验全过程的动态应变测试技术，分析埋地管道在不同的管道-落石偏移距离(管-石偏距)下的动力响应特征，提出基于管-石安全临界偏距的埋地油气管道安全评价方法. 结果表明，在正上方落石冲击作用下，管道截面主要呈现顶部受拉、侧面受压的变形模式. 当管-石偏距从0 m增加至2 m时，管道顶部环向峰值应变从12.5 × 10?6迅速降低至3 × 10?6以下，整体呈现出随管-石偏距的增加而衰减且衰减速率不断减小的基本规律. 建立描述两者关系的幂律模型表达式，该幂律关系与足尺模型试验结果和其他文献中的室内试验结果吻合良好. 根据管道屈服应变，提出基于管-石安全临界偏距的埋地油气管道安全评价方法.

Abstract:

The dynamic response characteristic of the pipeline under the impact of rockfall was analyzed in order to reasonably evaluate the safety of oil and gas pipeline project affected by rockfall in mountainous area. The dynamic response characteristic of buried pipelines under different pipeline-rock offset distances was analyzed combined with dynamic strain measurement technique throughout the testing process by conducting full-scale model tests of buried oil and gas pipelines subjected to rockfall impacts. A safety evaluation method for buried oil and gas pipelines based on the pipeline-rock critical safety offset was proposed. Results show that the pipeline cross-section primarily exhibits a deformation mode with tension on the top and compression on the sides under the impact of a rockfall from directly above. The peak circumferential strain at the top of the pipeline rapidly decreases from 12.5 × 10?6 to below 3 × 10?6 as pipeline-rock offset distance increases from 0 m to 2 m, showing a general trend of attenuation with increasing pipeline-rock offset distance, where the rate of attenuation continuously decreases. A power-law model was developed to describe their relationship, which accorded well with the results from the full-scale model tests and laboratory test results from other literature. A safety evaluation method for buried oil and gas pipelines based on the pipeline-rock critical safety offset distance was proposed based on the yield strain of the pipeline.
Key words: oil and gas pipeline    rockfall impact    dynamic response    full-scale experiment
