摘要:
水闸工程作为防洪减灾、调控水资源的重要设施，其安全运行至关重要。为复核水闸水力性态、掌握稳定性能，以二河枢纽入海水道二期加固工程为例，针对拟建水闸开展设计论证分析，通过计算得出不同工况下，闸基、闸侧水平段和出口段渗透坡降均分别小于其允许渗流坡降，渗透稳定满足现行技术规范要求。采用朗肯公式计算岸墙稳定，结果表明地基经处理后，承载力可满足规范要求。分基本组合和特殊组合计算闸室应力与稳定性，结果表明不同工况下闸基承载力满足要求，抗滑稳定性系数均高于规范允许值，且具有一定安全裕度，闸基处于稳定状态。研究成果可为水闸工程后续设计施工提供计算依据。
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.
