摘　　要：新疆ZG水电站工程泄洪冲沙闸建于深厚覆盖层上,闸室渗流控制问题尤为显著。结合本工程,通过大型商用有限元软件ABAQUS,建立混凝土护坦、连接板、防渗墙、泄洪冲沙闸、砂砾石覆盖层的三维模型用于渗流计算,分析不同工况条件下上述结构渗透稳定性与渗漏量。结果表明,在不同工况下,渗透稳定性及渗漏量均满足要求,可保证泄洪冲沙闸整体稳定性以及安全运行。分析结果可为今后同类型工程提供借鉴。The flood discharge and sand flushing sluice of Xinjiang ZG hydropower station project is built on deep overburden,and the seepage control problem of sluice chamber is particularly significant.Combined with the project,a three-dimensional model of concrete apron,connecting plate,cut-off wall,flood discharge and sand flushing sluice and sand gravel overburden is established through the large-scale commercial finite element software ABAQUS for seepage calculation,the seepage stability and leakage of the above structures under different working conditions are analyzed.The results show that the seepage stability and leakage meet the requirements under different working conditions.It is very important to ensure the overall stability and safe operation of flood discharge and sand flushing sluice,so as to provide reference for similar projects in the future.
