Abstract
As an important facility for flood control,disaster reduction,and water resource regulation,the safe operation of sluice projects is crucial.To review the hydraulic behavior and grasp the stability performance of the sluice,taking the second phase reinforcement project of the seawater inlet channel of the Erhe Hub as an example,this paper carries out design demonstration and analysis for the proposed sluice.Through calculations,it is concluded that under different working conditions,the seepage gradients of the sluice foundation,the horizontal section on the sluice side,and the outlet section are all respectively smaller than their allowable seepage gradients,and the seepage stability meets the requirements of current technical specifications.The stability of the shore wall is calculated using the Rankine formula,and the results show that the bearing capacity of the foundation after treatment can meet the requirements of the specifications.The stress and stability of the sluice chamber are calculated based on basic and special combinations.The results show that the bearing capacity of the sluice foundation meets the requirements under different working conditions,and the anti-sliding stability coefficient is higher than the allowable value in the specifications,with a certain safety margin.The sluice foundation is in a stable state.The research results can provide calculation basis for the subsequent design and construction of water gate projects.关键词
