摘　　要：气液两相流的不稳定流动和管道变形之间的相互作用,极大地改变了流体管道系统的特性,促进了气液两相流管道流固耦合的研究进程。概述了国内外单相输流管道流固耦合研究现状,重点阐述了海洋立管气液两相混输中严重段塞流的流动规律及其流固耦合问题的研究情况,评述了输流管道流固耦合的常用数值计算方法。分析了当前气液两相瞬变流流固耦合研究中存在的问题,展望了其发展前景。The reciprocity between unstable flow of gas-liquid two-phase flow and pipeline distortion changes the characteristic of a liquid pipeline system greatly and accelerates a process in research of liquid-solid coupling of a gas-liquid two-phase flow pipeline.The paper summarizes the research situation in liquid-solid coupling of single phase flow pipelines at home and abroad,and expounds its research stress on rule of severely slag flow in gas-liquid two-phase flow of offshore riser and its liquid-solid coupling problem,and states a calculating method for commonly used values in liquid-solid coupling of flow pipelines.Also,issues existed in research of liquid-solid coupling of transient flow in gas-liquid two-phase flow are analyzed and its developing prospect are given.
