Buckle propagation flattens the pipeline, creating collapse of pipeline along its passage. It eventually leads to the structural failure of the entire pipeline, causing great economic loss and environmental pollution.
海底管道受到海水的静水压力作用时可能产生局部屈曲,当静水压力超过其屈曲传播压力时,该局部屈曲将会沿着管道轴线传播,使管道变平崩溃,令管道整体结构失效,从而造成巨大的经济损失和环境污染。
