航道建设涉及水利、航运、城建等各个部门的利益,由于行业差异,各部门对航道建设有不同的认识,孰是孰非唯有通过计算分析才有定论,本文利用水力学圣维南方程组数值解方法分析论证东平水道航道建设工程措施对河道行洪安全的影响,试图使人们对河道水工程建设看法一致。计算结果表明,石坝整治使河道行洪水位有所提高,局部流速增大,影响行洪;裁弯工程、疏浚挖泥、炸礁清障等措施,使水位普遍降低,对行洪安全存在有利影响。扬长避短,因地制宜,是更好地发挥河道综合利用效益行之有效的治理措施。
The construction of watercourse involves the interests of various departments such as water conservancy, shipping and urban construction. Due to the differences among different industries, all departments have different understandings on the construction of watercourse. What is right and what is right? Only through calculation and analysis can we conclude that this article uses the formula of Shengweinan Equation The numerical solution method is used to analyze and verify the influence of Dongping waterway construction engineering measures on the flood safety of the river, trying to make people agree on the waterway construction. The calculation results show that the dam flood control improves the flood level of the river course and increases the local flow velocity, which affects the flood discharge. The measures such as cutting the dredging project, dredging dredging, Beneficial effect Foster strengths and weaknesses, according to local conditions, is to better play a comprehensive utilization of river effective governance measures.
