昆明主城现状条件下小洪水防洪调度方案研究
|
摘要
昆明主城所处地理位置特殊,由于受诸多因素的影响,城市防洪压力异常严峻。通过对纵穿昆明主城的盘龙江在加入外流域调水条件下的洪水进行分析,结合盘龙江现状行洪能力及存在问题,分析盘龙江主要防护对象昆明主城在安全泄量条件下的雨量,以此作为预警指标,提出盘龙江现状行洪能力条件下小洪水的洪水调度方案,以期通过发挥水文气象监测、预警、预报及洪水调度等非工程措施的效益,减缓昆明主城防洪压力,达到科学指导昆明主城洪水调度、最大限度减轻城市洪涝灾害的目的。
Kunming City proper is located in a special geographical position,which has the flood discharge of Songhuaba Reservoir in the upper reaches,the flood discharge capacity of the middle reaches of the river,and the entry of the interbasin water transfer and the flood pushing of Dianchi in the lower reaches,the constantly changing of underlying surface with urban development ect,it leads to the abnormal severity of urban flood control pressure. In order to put forward the flood control scheme under the condition of current flood discharge capacity of the Panlong River,in this paper,the flood of the Panlong River,which runs through the main city of kunming,is analyzed under the condition of water diversion in the external watershed,and combined with existing problems,the rainfall warning index of the main protection object under the condition of safe discharge is analyzed. It is expected to slow down the flood control pressure of the City of Kunming proper by giving full play to the benefits of non-engineering measures,such as hydrometeorological monitoring,early warning,forecasting and flood dispatching,and to achieve scientific guidance of kunming urban flood dispatching,utmost reduce the purpose of urban flood disaster.
