摘　　要：受下游大溶江洪水顶托影响,灵渠水文站流量整编的水位流量关系曲线采用连时序法绳套关系,基本上每场较大单峰洪水形成单一绳套的水位流量关系曲线,复式峰洪水形成连续的绳套水位流量关系,有时一年需制定多达10个绳套的水位流量关系曲线,连时序法绳套的水位流量关系需要实测流量点子较多,定线推流才能达到规定的标准,因此该站流量监测工作任务繁重,而且给资料整编推算流量增加许多工作量及难度。本文着重根据该站水力特性,科学使用流量测验及资料整编新技术,探讨该站受洪水顶托影响的流量测验和整编工作的对策和建议。Due to the backwater effect of flood in downstream Darongjiang River,the water level-flow relationship curve was compiled at Lingqu Hydrological Station by use of the continuous time series method to establish a rope loop relationship.Basically,each large single-peak flood forms a single rope loop water level-flow curve;com⁃pound-peak floods form continuous loops of water level-flow relationship.Sometimes it is necessary to develop wa⁃ter level-flow relationship curves of up to 10 rope loops per year.The water level-flow loop relationship processed by continuous time series method requires a large number of measured flow points,only based on which can the alignment and flow reckoning satisfy the specified standard.The flow monitoring work of Lingqu Hydrological Sta⁃tion is heavy.Moreover,it adds a lot of workload and difficulty to the data processing and flow calculation.Accord⁃ing to the hydraulic characteristics of this station,new technologies of flow measuring and data processing were used scientifically.Countermeasures and suggestions were discussed for the flood backwater effect on flow measuring and data processing.
