摘　　要：为分析水电站地下输水管道整体结构在土压力、温度、地震等多荷载复杂环境下内力的变化情况,采用ANSYS实体单元模拟了输水管道整体结构,运用五点法提取了相应内力,绘制了结构内力包络图,并进行了配筋设计及裂缝校核,进而综合分析了温度荷载、地震荷载及管道横截面形式等因素对管道整体结构内力的影响。研究结果对地下输水管道设计与施工具有一定的参考价值和指导意义。In order to analyze the internal force change for the whole structure of underground water pipeline in hy- dropower station under complex environment with multiple loads, such as earth pressure load, temperature load, seismic load, ANSYS solid elements is used to simulate the whole structure of water pipeline. Corresponding internal force is ob- tained by five-point method. The envelope diagram of structure internal force is drawn and the reinforcement design and crack check has been implemented. The influence of temperature loading, seismic loading and water pipeline cross section form on internal force of pipeline whole structure is analyzed comprehensively. The study result provides useful guidance for design and construction of underground water conveyance pipeline.
