摘　　要：黄河是一条河水高含砂、主槽善摆动、河床多流路、两岸大滩地的河流,是典型的地上悬河,此类特殊的河流水环境条件,对黄河下游穿黄输气管线工程的设计、施工等方面都会产生重大影响,根据黄河下游多条穿黄输气管线工程的施工经验,研究黄河下游穿黄输气管线工程遇到的环境风险技术问题,这些问题主要有黄河河道稳定问题、洪水揭底冲刷问题、地震液化与震陷、黄河根石问题、水、土腐蚀性问题等,研究成果可以为跨河桥梁、特高压输电线路、穿河通信管线等其他穿黄工程的设计和施工提供参考。The Yellow River is a river with high sand content,good swing in its main channel,multi-channel riverbed and large beaches on both sides,and it is a typical river hanging above the ground.Such special river water environment conditions will have a great impact on the design and construction of the gas pipeline project in the lower Yellow River.Based on the construction experience of several gas pipeline projects in the lower Yellow River,the technical problems of environmental risks encountered in the gas pipeline project in the lower Yellow River are studied.These problems mainly include the stability of the Yellow River channel,the erosion of the bottom of the flood,earthquake liquefaction and earthquake liquefaction,the root stone of the Yellow River,the corrosiveness of water and soil,etc.The research results can provide reference for the design and construction of other projects crossing the Yellow River,such as bridges across the river,extrahigh voltage transmission lines and communication pipelines across the river.
