摘要
由于经济发展的需要,在芜湖县红杨镇方山村上街附近拟建青弋江特大桥.按照设计方案,根据桥梁对河道防洪安全的影响,进行防洪评价计算.通过水文分析计算、冲刷与淤积分析计算以及岸堤的稳定性分析计算等,分析工程项目对河道的行洪、河势的稳定、防汛抢险工作、堤防安全、周边环境以及河道通航能力的影响,并提出防治与补救措施,包括对河道行洪能力的补救措施,河道岸坡影响的防治措施以及对防洪大堤影响的防治措施等.
Abstract
Qingyijiang grand bridge was planned to be built nearby Shangjie Street,Fangshan Village,Hongyang Town,Wuhu County.According to the design scheme and influence of bridge on flood control,the ability of flood control of the bridge was calculated.Through hydrological analysis and calculation,scour and deposition analysis,embankment stability calculation,effects of the project on flood carrying capacity,stability of river regime,emergency protection in flood defense,embankment safety,surrounding environment and river navigation ability were studied.Prevention and remedial measures were proposed,including remedial measures of flood carrying capacity,river slope impact mitigation measures,as well as control measures of flood control embankment.
