摘　　要：针对金湖县城西河活水工程节制闸工程加固设计方案开展参数优化,利用仿真计算平台建立计算模型,经模拟,锚固洞部位拉应力为最大,锚固洞、闸顶平台最大拉应力与纵向间距参数为正相关,但锚固洞最大拉应力与横向间距参数呈二次函数关系,且为负相关;闸顶平台最大拉应力受横向间距参数影响较小,稳定在1.03MPa;锚块最大拉应力受纵向设计参数抑制影响,间距增大20mm,平均可削弱其14.7%的拉应力,但其受横向间距参数影响较小,稳定在1.5MPa。特征部位最大压应力虽纵向设计参数为递增,但横向间距参数影响下锚块、锚固洞变化较小,稳定在11.2MPa、15.8MPa,闸顶平台在横向间距90mm后递减。研究认为纵向、横向设计参数分别为160mm、100mm时加固方案最优。Parameters are optimized aiming at the strengthening design scheme of Chengxihe runoff water project regulating sluice project in Jinhu County.The calculation model is established based on the simulation computing platform.The tensile stress of the anchor hole site is the maximum.The maximum tensile stress of the anchor hole and the sluice top platform is positively correlated with the longitudinal spacing parameters.However,the anchor hole maximum tensile stress and the transverse spacing parameters show quadratic function relation,and they are negatively correlated.The maximum tensile stress of the sluice top platform is less affected by the transverse spacing parameters,which is stable at 1.03MPa.The maximum tensile stress of the anchor block is inhibited by the longitudinal design parameters.The spacing is increased by 20mm,and the tensile stress can be weakened by 14.7%on average.However,it is slightly affected by the transverse spacing parameters,which is stable at 1.5MPa.Although the longitudinal design parameters of the maximum tensile stress in the characteristic site is gradually increased.However,the change of the anchor block and the anchor hole is small under the influence of the transverse spacing parameters,which is stable at 11.2MPa and 15.8MPa respectively.The maximum tensile stress of the sluice top platform is gradually decreased at the transverse spacing of 90mm.It is considered that the reinforcement scheme is optimal when the longitudinal and transverse design parameters are 160mm and 100mm respectively.
