注莲塘闸抗滑稳定及防渗分析

Analysis of anti-sliding stability and anti-seepage of Zhuliantang sluice

文章基于AutoStable和AutoBank软件,对南陵注莲塘闸进行抗滑稳定和防渗分析。考虑闸室自重、上下游水压力、闸室及启闭设备集中荷载、交通桥均布荷载等的影响,通过分析作用于闸底板的扬压力,继而对闸室的抗滑稳定系数进行计算;通过具体定量分析,注莲塘闸在设计工况和最不利工况下抗滑稳定系数等符合规范要求;通过渗流稳定分析,水闸的水力坡降满足地勘资料允许值。注莲塘闸的抗滑稳定及抗渗分析为其后续的安全运行提供了保证,也为其他水闸的抗滑稳定及防渗分析提供一定借鉴。

Based on AutoStable and AutoBank software,article analyzes the anti-sliding stability and anti-seepage of Zhuliantang sluice in Nanling.Considering the influence of the body weight of the lock chamber,the water pressure,the concentrated load of the lock chamber and the opening and closing equipment,and the uniform load of the traffic bridge,the lifting pressure acting on the gate floor is analyzed,and then the anti-sliding stability coefficient of the lock chamber is calculated.The concrete quantitative analysis shows that the stability coefficient of Zhuliantang gate in the design condition and the most unfavorable condition meets the specification requirements.Through seepage stability analysis,the hydraulic gradient of sluice meets the allowable value of geological prospecting data.The antisliding stability and anti-seepage analysis of Zhuliantang sluice provides a guarantee for its subsequent safe operation,and also provides some reference for the anti-sliding stability and anti-seepage analysis of other sluice.
