城市排水管网模型模拟结果准确性的便捷校验方法

Convenient checkout method on simulation results of urban drainage pipe network model

数学模型法在城市排水工程领域中的应用日益广泛,对于结果准确性的判别也逐渐成为关注的焦点。提出了一种城市排水管网模型模拟结果的便捷校验方法,可在不具备常规模型校验条件时对模拟结果的准确性进行较为便捷的判断。案例分析表明,恰当地应用本方法可为模型模拟结果的判定提供可信参考依据。与此同时,针对本方法可能存在的局限性,提出了可通过对多工况、多场次降雨事件的模拟结果进行综合分析验证来规避存在错误的模型偶发性验证通过的可能。

Mathematical model method has been gradually applied in urban drainage engineering field.And the reliability of model simulation results has attracted more and more attention.In the present study,a convenient checkout method on the simulation results of urban drainage pipe network model was put forward,which would help to validate the simulation results when actual data are not available.The case study illustrated that applying this method properly could provide convincing proof for the reliability of model simulation results.Meanwhile,the limitation of this method were also discussed,which could be overcome by comprehensive analysis after multiple simulations with different rainfall events and work conditions.
